In a way that indicates bad luck or misfortune; unfortunately.

Unluckily → It is formed from "un-" (meaning not) and "lucky" (from Middle English *lucki*, meaning fortunate or having good luck) and the suffix "-ly" (meaning in a manner). The word "unluckily" means in a manner that is not fortunate or lacking good luck.
Think of 'not' ('un-') being added to 'lucky' to remember that 'unluckily' means in a way that is not fortunate.
