KK: /ˈweɪvərər/
A person who is indecisive or uncertain, often changing their mind frequently.
As a waverer, she struggled to choose between the two job offers.
Waverer → It is formed from "waver" (from Old English "wafrian", meaning to fluctuate or sway) and "-er" (meaning a person who). A waverer is a person who fluctuates or is indecisive.
Think of someone who is 'swaying' or 'fluctuating' in their decisions — that's why a waverer is someone who can't make up their mind.
