Meaning: smell

Illustrative Context

I (can) smell smoke.

Perceiving an odour, by a human, through the nose.
Not emitting an odour, smelling of something, e.g. a flower. So not as in the food smells good.
The transitive verb (form) used where the subject of the verb is the person who perceives the odour, while that odour, or the substance or thing emitting it, is the object.
Some languages (e.g. Slavic) have different verbs depending on whether the human subject is taken as either the experiencer or the agent (the same contrast that English itself has for other perception meanings such as see vs. look or hear vs. listen). In such languages, select the verb form where the human subject is experiencer, not agent, who perceives the odour passively, not actively and intentionally 'sniffing' for it. So not as in she knelt down and smelt the flowers.
Some languages do not have a specific verb uniquely for perceiving odours through the nose, as distinct to perceiving by other senses such as taste or touch, and so on, and use a more general ‘sense’ verb instead, e.g. French sentir (for English smell and feel). In such languages, just select that more generic lexeme if it also covers the target sense here, as per the general IE-CoR policy.
