pesky
Pesky is an adjective used to describe something or someone that is bothersome, irritating, or difficult to deal with. The term originates from the Old French word "pestifère," which means "full of pestilence" or "full of plague." Over time, the meaning evolved to describe something that causes annoyance or trouble. In modern usage, "pesky" is commonly used to describe small, often annoying creatures such as insects, but it can also be applied to people, tasks, or situations that are irritating or problematic. For example, a pesky mosquito might be one that bites frequently, or a pesky task might be one that is particularly difficult or time-consuming. The term is often used in a lighthearted or humorous context, but it can also carry a sense of mild frustration or exasperation. Despite its negative connotation, "pesky" is generally used to describe things that are not serious or life-threatening, and it is often employed in a way that is meant to be amusing or endearing.
