IPA: //ʌnˈsɔːt//
KK: /ʌnˈsɔt/
Something that is not looked for or requested; it happens without being asked for.
She received some unsought advice from her friends.
Unsought → It is formed from "un-" (meaning not) and "sought" (the past participle of "seek", from Old English "sēcan", meaning to search for). The word "unsought" means not being searched for or desired.
Think of 'not' ('un-') wanting to 'search for' ('sēcan') something — that's why unsought means something that is not desired or looked for.
