Not easy to deal with or causing problems; something that makes things more difficult or troublesome.
The road closure was inconvenient for many drivers.
Inconvenient → It is formed from "in-" (meaning not) and "convenient" (from Latin "conveniens", meaning suitable or fitting). The word "inconvenient" means not suitable or causing difficulty.
Think of 'not' ('in-') being added to 'suitable' ('convenient') — that's why inconvenient means something that is not suitable or causes trouble.
