IPA: /ˈɒn.sɛt/
KK: /ˈɑnˌsɛt/
The beginning or start of something, often used to describe the initial stage of an event or condition.
The onset of winter brought cold temperatures and snow.
Onset is derived from the Old English "onsettan" (meaning to set upon or attack). The word combines "on-" (meaning upon) and "settan" (meaning to set or place). Thus, "onset" refers to the act of setting upon or beginning something, often with a sense of force or attack.
Think of 'setting upon' something to remember that 'onset' means the beginning or attack of an event.
