- Do not confuse with 'активист' (activist).
Common Mistakes
- Using 'activator' for a person who is simply active or energetic (use 'activist' or 'energetic person').
- Confusing 'activator' (causes action) with 'accelerator' (increases speed of existing action).

FAQ
Frequently Asked Questions
In chemistry, they are similar but not identical. A catalyst speeds up a reaction without being consumed; an activator is a specific type of catalyst or agent that initiates or enables a process, often by binding to an enzyme or receptor.
Metaphorically, yes, especially in business or leadership contexts (e.g., 'She was the activator of the new initiative'). In technical/scientific contexts, it typically refers to non-human agents.
The most direct opposite is 'inhibitor' or 'repressor'—something that decreases, blocks, or prevents activity.
It is common in scientific, technical, and certain business fields, but it is not a high-frequency word in everyday general English.
