IPA: /ˈræŋkər/
KK: /ˈræŋkər/
A person who has been promoted to a higher position, especially in the military, often from a lower rank or enlisted status.
The ranker received a medal for his bravery during the mission.
Ranker → The word is formed from "rank" (from Old French *ranc*, meaning a row or line) and "-er" (meaning a person who). A ranker is a person who ranks or is ranked in a certain order.
Think of someone who is placed in a specific 'row' or 'line' ('rank') — the '-er' indicates that this person is doing the ranking.
