C2Technical / Scientific / Formal Figurative
Definition
Meaning
A substance or agent that decreases the rate of a chemical reaction.
In broader contexts, a person, event, or factor that slows down or hinders a process, change, or development.
Linguistics
Semantic Notes
Primarily a technical chemistry term (inhibitor, negative catalyst). In metaphorical use, it implies an active force that prevents or retards progress, distinct from a mere absence or neutral factor.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. The term is equally technical in both varieties.
Connotations
Identical technical connotations. In figurative use, may carry a slightly stronger pejorative sense in American business/political discourse.
Frequency
Equally low frequency in both varieties, confined to specialised and figurative formal contexts.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque "негативный катализатор" in non-chemical contexts; use "тормоз", "препятствие", "сдерживающий фактор" instead.
- Do not confuse with "negative factor" which is broader and less active.
Common Mistakes
- Using it to mean simply a 'bad outcome' rather than an active slowing agent.
- Confusing with 'catalyst' (positive) and omitting 'negative'.
- Using in overly casual contexts where 'obstacle' or 'problem' is sufficient.

FAQ
Frequently Asked Questions
Yes, in chemistry, 'negative catalyst' is a synonym for 'inhibitor' – a substance that decreases the rate of a reaction.
It can be used figuratively in formal or business contexts, but it's quite specialised. Words like 'obstacle', 'brake', or 'hindrance' are more common in everyday speech.
A 'problem' is a general difficulty. A 'negative catalyst' specifically implies an active agent that causes a process to slow down or deteriorate over time.
No, it is not standard. The fixed technical and figurative term is 'negative catalyst'. 'Bad catalyst' is non-standard and ambiguous.
