IPA: /ˈɒnˌlʊkɪŋ/
KK: /ˈɑnˌlʊkɪŋ/
Describing someone who is watching or observing something happening, often without participating.
The onlooking crowd cheered as the performers took the stage.
Onlooking → It is formed from "on" (meaning in a position of) and "look" (from Old English "locian", meaning to see or observe) and the suffix "-ing" (indicating the action or process). The word "onlooking" means the action of observing or watching from a position of presence.
Think of being 'in a position of' ('on') and 'seeing' ('look') — that's why onlooking means to observe or watch.
