KK: /ˈkɪŋˌmeɪkər/
A person who has the power to influence the selection of a leader or candidate, especially in politics.
The wealthy businessman was seen as a kingmaker in the upcoming election, helping to choose the next mayor.
Kingmaker → It is formed from "king" (from Old English "cyning", meaning a male monarch) and "maker" (from Old English "macian", meaning to make or create). The term "kingmaker" refers to a person who has significant influence in the selection or appointment of a king, often without seeking the throne themselves.
Think of someone who 'makes' or influences a 'king' — that's why a kingmaker is someone who helps choose a ruler.
