IPA: /ˈsuːtə/
KK: /ˈsutɚ/
A man who is trying to win the affection of a woman, often with the intention of marriage.
He was a charming suitor who brought flowers and wrote poetry for her.
Suitor is derived from the Old French word 'suitor' (meaning one who follows or pursues). The root 'suit' comes from the Latin 'sequi' (meaning to follow). The suffix '-or' indicates a person who performs an action. Thus, a suitor is a person who follows or pursues someone, typically in the context of seeking a romantic relationship.
Think of someone who 'follows' ('sequi') another person in pursuit of love or affection — that's why a suitor is someone who pursues a romantic interest.
