IPA: /bɪˈsɛtɪŋ/
KK: /bɪˈsɛtɪŋ/
Always bothering or attacking someone or something.
The besetting problems of the project made it difficult to succeed.
Besetting is formed from "be-" (meaning about or around) and "set" (from Old English "settan", meaning to place or put). The word describes the act of surrounding or placing oneself around something persistently, often in a troublesome manner.
Think of being 'around' ('be-') something that is 'placed' ('set') persistently, which helps you remember that besetting refers to something that troubles or surrounds you.
