Smelled or Smelt? The Past Tense of Smell Depends on the Accent
On this page
You're doing dictation practice on a conversation in a kitchen. The speaker lets out a sentence, you write it down as "The kitchen smell of garlic," and the correction marks the third word wrong in red. The real sentence is "The kitchen smelled of garlic." Another time you're reading a story by a British author, you see "the room smelt damp," and you wonder whether you've just run into a typo or a different form. Quick answer first: the simple past of smell is smelled, and the past participle is also smelled. In British English, both of those positions also have a parallel variant that's used side by side: smelt.
The hard part of smell sits in two places, and neither is a matter of memorizing a table. The first is choosing the form: smelled or smelt, which one in an exam, which one in an email, which one when talking to a British colleague. The second, and heavier for anyone training their listening, is the final consonant cluster. smelled ends in /ld/, smelt ends in /lt/, and both clusters are the fastest kind to dissolve in speech at normal speed. When that ending drops, "it smelled bad" and "it smells bad" end up separated by just a /z/ sound that you won't catch either.
This article goes through that whole chain: the form table for smell, the verb group it belongs to and why that whole group has two endings, when to use smelled and when to use smelt, smell's own particular meaning trap with of and like, common combinations, and — the longest part — how these two forms actually sound when native speakers talk normally. There's one more detail near the end of the article that few pages mention: smelt is also a completely different verb, with nothing to do with the nose.

The form table for smell, and the two-ending verb group
Five forms. The pronunciation column is given in the American accent, with the British split marked where it differs.
| Form | Word | Pronunciation | Short example |
|---|---|---|---|
| Base form (V1) | smell | /smel/ | These flowers smell nice. |
| Third person singular | smells | /smelz/ | It smells like rain. |
| Simple past (V2) | smelled | /smeld/ (British also uses smelt /smelt/) | I smelled smoke. |
| Past participle (V3) | smelled | /smeld/ (British also uses smelt /smelt/) | Have you smelled this? |
| Present participle | smelling | /ˈsmelɪŋ/ | The dog is smelling the bag. |
smell isn't an irregular verb in the usual sense. It's a regular verb, adding -ed normally, and because the root ends in the voiced sound /l/, the -ed ending is pronounced /d/, not /ɪd/. The rule is only one line long and worth memorizing: only roots ending in /t/ or /d/ add an extra syllable as /ɪd/. smell ends in /l/, so smelled stays one syllable, exactly smell plus a /d/ sound tacked on the end.
What makes smell distinctive is that it belongs to a small group where two endings coexist. This group includes learn and learnt, burn and burnt, dream and dreamt, spell and spelt, spill and spilt, lean and leant, leap and leapt, spoil and spoilt, kneel and knelt, and smell and smelt. Look closely and you'll see all the roots in this group end in a sonorant consonant: /l/, /n/, /m/, /p/. That's not a coincidence. The old past-tense ending in English, when following these sounds, got choked into a /t/ sound, and the -t spelling preserves that old shape.
What happened next is that the two sides of the Atlantic went two different ways. American English standardized almost the entire group to -ed, so in the US you get smelled, learned, burned, dreamed. British English kept both forms and uses both, with the -t form sounding more natural in everyday speech, while the -ed form shows up more in modern writing. Neither form is wrong, and neither is an old form that's died out.
One small detail worth noting: in this group, most pairs differ only in the final consonant, while the vowel stays the same. smelled /smeld/ and smelt /smelt/ both have the vowel /e/. But there are two exceptions that change the vowel too, and that's where learners often get tripped up: dream has dreamed /driːmd/ with a long vowel, and dreamt /dremt/ with a short vowel. leap works the same way, with leaped /liːpt/ and leapt /lept/. smell is well-behaved — its two forms sound nearly identical.
If you're reviewing this whole group at once, the three closest relatives are worth reading alongside this one. The past tense of learn is the most classic case of the -ed/-t pair because learned has a third pronunciation on top of that when used as an adjective. The past tense of burn is worth a look because burnt has split off entirely to become an adjective while burned keeps the verb role. The past tense of dream is the one pair in the group that changes the vowel too, so learning to hear dreamt is a different exercise from learning to hear smelt. And if you want to lay out the whole system at once, the article on English grammar puts the tenses and verbs in their proper places.
When to use smelled, when to use smelt
Grammar rule first, form-choice rule after. Both smelled and smelt can do two jobs: stand alone as the main verb in the simple past, and follow have, has, had as the past participle. Whichever one you pick, you have to keep that role consistent, and after did both disappear because did already carries the past meaning.
| Sentence | Correct or wrong | Why |
|---|---|---|
| I smelled gas in the hallway. | Correct | Simple past, standard form in every accent |
| I smelt gas in the hallway. | Correct in British English | -t variant, natural for British speakers, unusual to American ears |
| She has smelled it already. | Correct | Participle following has |
| She smelled it already, she has. | Wrong | Patched-together sentence, participle and simple past stacked on top of each other |
| Did you smelled that? | Wrong | After did there must be the base form smell |
| The soup was smelled by everyone. | Wrong in ordinary context | smell is a sense verb, the passive sounds very forced |
As for choosing a form, here's practical advice: use smelled for everything you write. It's correct in both accents, no one will mark it wrong, and it matches the -ed reflex you already have. Keep smelt on the receiving end — that is, be able to recognize it and understand it when you meet it in British films, British books, BBC podcasts. In an IELTS Writing essay, smelt isn't counted as an error, but if you write smelt in one sentence and smelled in the next, the essay loses consistency, and that's where points actually get deducted.
smell's own meaning trap lies elsewhere, and it catches more people than the -ed versus -t issue. smell is both a perception verb with an object, and a linking verb. Those two roles lead to two different sentence patterns, and Vietnamese lumps both into the words "ngửi thấy" (to perceive by smelling) or "có mùi" (to have a smell).
| Sentence | Real meaning |
|---|---|
| I smelled the milk before I drank it. | I actively put my nose to it and sniffed, clear object |
| The milk smelled sour. | The milk was giving off a sour smell, smell is a linking verb, followed by an adjective |
| The room smelled of paint. | The room had a smell of paint, of points to a real source of the smell |
| The room smelled like paint. | The room smelled similar to paint, may not actually be paint |
| The bin smelled. | Nothing follows, the default meaning is an unpleasant smell |
| He smelled a rat. | He sensed something was fishy, figurative meaning, unrelated to smell |
The fifth row is the one most worth remembering. When smell stands alone, no adjective, no preposition, the sentence automatically carries a negative meaning. "Your shoes smelled" isn't a neutral remark. To say a pleasant smell, you must have an adjective following it: "Your shoes smelled fine."
The two rows with of and like are also worth pausing on. of points to the thing actually giving off the smell in the room, while like points to something used for comparison. "The soup smelled of fish" means there's fish in the pot. "The soup smelled like fish" means the smell made you think of fish, but what's actually in the pot isn't certain. Vietnamese speakers tend to use like for both, because the word "như" (like/as) is more convenient.
Hearing smelled and smelt in real speech
This is the part the verb table doesn't tell you, and it's also why you keep mistyping smelled even when you know it by heart. On paper, smelled has all seven letters. In speech at normal speed, its tail end is frequently just not there.
The /d/ ending disappears when the following word starts with a consonant. This is the single most important rule on this whole page. In "smelled bad," the /ld/ cluster runs straight into the /b/ that follows and the /d/ gets swallowed whole, so the sentence comes out as "smell-bad." In "smelled funny," you hear "smell-funny." The consequence is straightforward: in sentences like these, past and present sound exactly the same, and the only clue left is the other words in the sentence.
The /d/ ending only survives when the following word starts with a vowel. "smelled it" links into one block, "smel-dit." "smelled awful" becomes "smel-dawful." If you only ever catch smelled clearly in sentences like these, your ear is doing its job fine — the problem is that the other kind of sentence makes up most of them.
smelt and smelled are almost impossible to tell apart by ear in fast speech. Both are smell plus a stop sound at the end, differing only in whether it's voiced or voiceless, and a final stop consonant usually doesn't get released anyway. Listen to a British speaker say "it smelt of damp" and an American speaker say "it smelled of damp," and the difference you pick up is more likely to be their accent than that consonant.
The initial /sm/ cluster doesn't exist in Vietnamese. Vietnamese doesn't allow two consonants to sit together at the start of a syllable, so a new learner's ear tends to slip in an extra vowel and hear smell as two syllables, or drop the /s/ entirely and hear "mell." When a sentence runs fast, "I smelled" can come out almost as "ai-smeld" fused into one block, and you lose the boundary between the two words altogether.
A singular subject makes everything messier. "It smells" ends in /lz/, "It smelled" ends in /ld/. These two are still distinguishable at the end of a sentence; in the middle of a sentence, before a consonant, they both drop and all that's left is "it smell."
have and has before smelled are practically invisible. "I have smelled that before" in real speech is "I've smelled that before," and the 've part is just a /v/ sound stuck onto the end of the subject. Miss that bit and you'll write down "I smelled that before" — a sentence that's still grammatically correct but in the wrong tense, so the dictation checker will mark it wrong and you won't understand why.
The table below lines up three things side by side: the actual sentence, how it sounds when spoken fast, and how learners tend to mistranscribe it. The middle column shows you how the sentence sounds in real life, not its standard phonetic transcription.
| Actual sentence | Sounds like | Learners often write it as |
|---|---|---|
| The whole flat smelled damp. | ...flat smell-damp | The whole flat smell damp. |
| I smelled it the moment I walked in. | ai smel-dit thuh moment... | I smell it the moment I walked in. |
| It smelt of wet dog in there. | i smel-tuv wet dog... | It smell of wet dog in there. |
| Has anyone smelled the gas? | hz eniwun smeld thuh gas | Has anyone smell the gas? |
| She's smelled worse things. | shiz smeld wors things | She smelled worse things. |
| Something smelled off in the fridge. | sumthin smell-doff... | Something smell off in the fridge. |
Look at the third column and the mistakes fall into three tidy categories. The first is the /d/ ending dropped before a consonant, accounting for four of the six lines, and this is a listening error, not a grammar error: you know perfectly well that the past tense needs -ed, your ear simply never received that signal. The second is linking in the wrong place, as in the "smelled off" line getting split into "smell doff." The third is dropping an unstressed function word, namely the has or 's at the start of the sentence.
In a dictation session on WELE, this exact chain of correction played out with smell itself. You hear a sentence, transcribe it as is, and the checker flags that you wrote smell where it should have been smelled. The information you get isn't "you forgot to conjugate the verb" — it's "there's a /d/ sound here that your ear hasn't caught yet." Those two diagnoses lead to two completely different actions. The first sends you back to review the verb table. The second sends you back to listen to that exact sentence again, and this time you know to pay attention to the gap between smell and the next word.
The crucial point is that you need to encounter that exact type of sentence over and over, not just once. A smelled sitting before a vowel is easy — you catch it right away. A smelled sitting before a consonant is the one that needs practice, and only real listening volume gives you enough repetitions. Reread the five-line table at the top of this article ten times and your ear stays exactly the same.
If you want to understand the mechanism behind final sounds getting swallowed, the connected speech article explains this phenomenon across whole sentences, not just for smelled. And if you want to try it directly on real sentences, the podcast library has transcripts ready for you to check against after each dictation attempt.
Common combinations and collocations with smelled
smell has almost no true phrasal verbs. Aside from smell out, meaning to track something down, you won't find a whole family of smell up, smell off, smell over. What you need to memorize instead are fixed combinations: which prepositions smell pairs with, which adjectives, and which set idioms it appears in. The thirteen lines below are written in the past tense so you get used to seeing that form.
| Combination | Meaning | Example |
|---|---|---|
| smelled of | Gave off the smell of that very thing | His coat smelled of cigarettes. |
| smelled like | Had a smell similar to, comparative | The air smelled like rain. |
| smelled good / nice | Smelled pleasant, nice | Whatever she was cooking smelled good. |
| smelled bad / awful | Smelled unpleasant, hard to bear | The bin smelled awful by Friday. |
| smelled off | Smelled spoiled, said of food | The chicken smelled off, so I threw it out. |
| smelled funny | Had an odd smell, not clearly identifiable | The water smelled funny that morning. |
| smelled burning | Caught the smell of something burning | I smelled burning and ran to the kitchen. |
| smelled smoke / gas | Caught the smell of smoke, caught the smell of gas | Someone smelled gas on the third floor. |
| smelled a rat | Sensed something suspicious was going on | She smelled a rat when the invoice arrived twice. |
| smelled blood | Sensed an opportunity as an opponent weakened | The other bidders smelled blood. |
| smelled out | Tracked down, discovered | The dog smelled out the missing bag. |
| smelled strongly of | Reeked strongly of something | The corridor smelled strongly of bleach. |
| smelled the same | Still had exactly the same smell as before | Ten years on, the workshop smelled the same. |
The last three lines of the table are worth noting because that's where smell leaves the nose behind. smelled a rat and smelled blood are both figurative, and both come up constantly in business news, crime films, interview podcasts. If you only learn smell in its literal sense, you'll hit a sentence like "the investors smelled blood" and picture something completely wrong.
One more point about structure. After smelled, an adjective follows directly, with nothing inserted: "it smelled good." But if you want to say you caught someone in the act of doing something, you need a completely different structure, smell + object + V-ing: "I smelled something burning." This sentence comes up a lot and the word something is exactly the part that tends to get dropped in transcription.
Mistakes Vietnamese speakers commonly make with smell
Writing smellt or smeld. This comes from knowing there are two forms but mixing them together. There are only exactly two correct spellings: smelled, with both l's and the -ed ending, or smelt, with both l's and a single t. There's no smellt, no smeld, no smellded.
Did you smelled that. After did, the verb goes back to the bare infinitive, because did is already carrying the past-tense meaning. The correct sentence is "Did you smell that?" This mistake tends to pop up exactly when you're focused hard on remembering that the past tense of smell needs an ending — and remembering it too well.
Reading smelled as two syllables. A lot of people pronounce "smell-ed" as if it added a new syllable. It doesn't. The root smell ends in /l/, and only roots ending in /t/ or /d/ produce an extra /ɪd/ syllable. smelled is one syllable, /smeld/. Say an extra syllable and listeners will still understand you, but your ear will keep listening for a syllable that doesn't exist when other people speak, and that's the real cost.
It smelled badly. When smell functions as a linking verb, what follows it is an adjective, not an adverb. "It smelled bad" is the correct one. The sentence "he smelled badly," read strictly, means his sense of smell is poor, and that's a sentence people almost never say.
Mixing smelled and smelt within the same piece of writing. Both are correct, but once you pick one, stick with it for the whole piece. In an essay, if the second sentence uses smelt and the eighth sentence uses smelled, that's a sign the writer is copying from two different sources. Choose smelled if you're not sure, since it's safe in every accent.
Confusing smelt meaning "odor" with smelt meaning "metalworking." This is a trap unique to this word, and few pages mention it. In English there's another verb smelt that's completely different, meaning to melt ore to extract metal, and it's a regular verb: smelt, smelted, smelted. So the sentence "they smelted iron here for two centuries" is about a smelting furnace, while "they smelt iron here" could, depending on context, be the present tense of smelting or the British past tense of smelling. On top of that, smelt is also the name of a small fish. When you come across this word in a reading passage, first look around to see whether the topic is cooking, a factory, or dinner.
Quick exercise
Eight sentences, fill in smell, smells, smelled, or smelling. Do them all first, then look down at the answer section.
- I ______ gas as soon as I opened the door.
- Did you ______ anything strange last night?
- This cheese ______ terrible, throw it away.
- The dog has ______ every bag in the room.
- The whole house ______ of fresh bread yesterday.
- She was ______ the flowers when I came in.
- Something ______ burning about ten minutes ago.
- Her coat still ______ of smoke every evening.
Answers: 1. smelled. 2. smell. 3. smells. 4. smelled. 5. smelled. 6. smelling. 7. smelled. 8. smells.
Sentences 2 and 8 are the two worth pausing on. Sentence 2 has did in front of it, so the verb goes back to the base form, and this is the most commonly made mistake among all eight sentences. Sentence 8 has the word still and every evening, meaning a habit that's still ongoing, so it has to take the present smells rather than the past, even though the sentence sounds like it's telling an old story. If you got these two wrong, the section above is worth reading through once more.
Frequently asked questions
What is the past tense of smell?
The simple past and past participle of smell are both smelled. In British English there's also the form smelt, used in parallel in both positions. Both are accepted, and smelled is the safe choice in every accent.
Smelled or smelt, which one is correct?
Both are correct. smelled is the standard form in the US and is also very common in Britain. smelt is a form that's still very much alive in spoken British English. If you're writing an exam essay or a work email, choose smelled and keep it consistent throughout.
Is smelled pronounced /smeld/ or /smelɪd/?
It's pronounced /smeld/, one syllable. The -ed ending only becomes its own syllable /ɪd/ when the root word ends in /t/ or /d/, for example wanted or needed. smell ends in /l/, so the ending is just a single /d/ sound tacked on.
What's the difference between smell of and smell like?
of points to the thing that's actually giving off the smell, while like points to something used for comparison. "The room smelled of paint" means there is actually paint in the room. "The room smelled like paint" means the smell reminds you of paint, but whether there's actually paint there is unknown.
Why do I hear a sentence with smelled and transcribe it as smell?
Because the /d/ sound at the end of smelled gets completely swallowed when the next word starts with a consonant. "smelled bad" comes out sounding like "smell bad". This is a listening error, not a grammar error, so the fix is to listen to that type of sentence many more times, not to relearn the conjugation table.
How do I know whether my ear has picked up on end sounds like /d/ yet?
The most practical way to measure it is to transcribe a few passages of dialogue and count how many places you dropped an ending. The listening level test leaves you a benchmark to compare against after a few weeks of practice.
You can read through the table of smell's forms in twenty seconds, and that's the easiest part of this page. The rest — the way the /d/ ending disappears before every consonant, and the way smelt is both a smell and a smelting furnace — only really sinks in once you mishear it and then see where you transcribed it wrong. Pick a short clip and try dictation practice on a passage containing smelled, then come back to the table at the top of this article and see if it still feels as dry.
