Definition
Meaning
A substance that has a smell; something that emits an odour.
In technical contexts, a chemical compound added to a product (like natural gas) to give it a detectable smell for safety. Also used in perfumery and flavourings.
Linguistics
Semantic Notes
Primarily a technical term. In everyday language, 'smelly substance' or 'scent' is more common. It is often used as a noun, but can function as an adjective meaning 'having an odour'.
Dialectal Variation
British vs American Usage
Differences
Spelling: UK English prefers 'odour', US English 'odor'. Therefore, 'odorant' is the standard spelling in US English, while 'odourant' is a possible but less common variant in UK English. The US spelling 'odorant' is dominant in international technical contexts.
Connotations
Neutral to technical in both varieties. No significant difference in connotation.
Frequency
Equally low frequency in both varieties, confined to technical/scientific registers.

Think: 'ODOR' + '-ANT' (like a participant). An odorant is an 'agent' that participates in creating an odour.
Conceptual Metaphor
AGENT (The odorant acts upon the environment to create a sensory signal).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'дезодорант' (deodorant), which is the opposite—it removes or masks odours. 'Odorant' is 'одорант' or 'пахучее вещество'.
- Avoid direct calque from 'ароматизатор' (flavoring/aromatizer) unless in a flavour context. 'Odorant' is broader.
Common Mistakes
- Using 'odorant' in everyday conversation instead of common words like 'smell' or 'scent'.
- Misspelling as 'odourant' in international technical texts where 'odorant' is standard.
- Confusing 'odorant' (causes smell) with 'deodorant' (removes/masks smell).
