Conversation

I was reading about how certain drugs act as a inhibitor in the body.

Really? That sounds interesting, what do they inhibit?

They can slow down chemical reactions, like stopping pain signals.

That makes sense! It's fascinating how our body works with these substances.

Root Explanation

Inhibitor → It is formed from "in-" (meaning not) and "habere" (meaning to have or hold) combined with the suffix "-tor" (meaning one who). The word "inhibitor" refers to something that prevents or holds back an action or process.

Memory Tip

Think of something that 'holds back' ('habere') or 'prevents' ('in-') an action — that's what an inhibitor does.
