A person or thing that causes paralysis or stops movement.
The doctor used a paralyzer to temporarily stop the patient's muscle movement during the procedure.
Paralyzer → It is formed from "paralyze" (from Greek "paralyein", meaning to disable or to loosen) and "-er" (meaning a person or thing that performs an action). The word "paralyzer" refers to a person or thing that causes paralysis or disables movement.
Think of someone or something that 'loosens' or 'disables' ('paralyze') — that's why a paralyzer is something that causes paralysis.
