Not relevant or appropriate to the situation or context.

Inapposite → It is formed from "in-" (meaning not) and "appositus" (from Latin, meaning placed near or appropriate). The word "inapposite" means not appropriate or not suitable for the situation.
Think of 'not' ('in-') being combined with 'appropriate' ('appositus') to remember that inapposite means something that is not suitable.
