In a way that causes difficulty or trouble.

Inconveniently → It is formed from "in-" (meaning not) and "convenient" (from Latin "conveniens", meaning suitable or fitting) and the suffix "-ly" (meaning in a manner of). The word "inconveniently" means in a manner that is not suitable or fitting.
Think of 'not' ('in-') being combined with 'suitable' ('convenient') to remember that 'inconveniently' describes something that is not suitable or fitting.
