Inexpediency → It is formed from "in-" (meaning not) and "expediency" (from Latin "expedientia", meaning usefulness or suitability). The word "inexpediency" means the state of being not useful or suitable for a particular purpose.
Think of 'not' ('in-') being combined with 'usefulness' ('expediency') to remember that 'inexpediency' refers to something that is not suitable or useful.
