A state or condition that causes difficulty or discomfort, often leading to trouble or annoyance.

Inconveniency → It is formed from "in-" (meaning not) and "convenient" (from Latin "conveniens", meaning suitable or fitting) with the suffix "-cy" (meaning state or condition). The word describes the state of being not suitable or causing trouble.
Think of 'not' ('in-') being combined with 'suitable' ('convenient') to remember that 'inconveniency' refers to a state of being unsuitable or troublesome.
