IPA: /ˈwɛəriər/
KK: /ˈwɛəriər/
More cautious or careful than usual, especially in avoiding danger or risk.
After hearing the news, she became warier about trusting strangers.
Warier → It is formed from "war" (from Old English *werre*, meaning conflict or battle) and the suffix "-ier" (meaning one who). The word "warier" refers to one who is more cautious or alert, often in the context of potential conflict or danger.
Think of someone who is more alert or cautious in a situation, like a soldier in a 'war' — that's why 'warier' means more cautious.
