IPA: /ˈbraɪdlər/
KK: /ˈbraɪdlər/
A person who controls or restrains something, similar to how a bridle is used to guide a horse.
The bridler of the wild horse was skilled in taming and training it.
Bridler is formed from "bridle" (from Old English *brīdel*, meaning a headgear for a horse) and the suffix "-er" (meaning a person who). A bridler is a person who uses or manages a bridle, typically in the context of controlling a horse.
Think of a person who uses a 'bridle' to control a horse — the '-er' indicates that this person is the one who manages or handles the bridle.
