IPA: /ˈbækˌsteɪ/
KK: /ˈbækˌsteɪ/
A support that helps hold up the back of something, especially in sailing where it connects from the mast to the back of the boat.
The sailor adjusted the backstay to ensure the mast was stable during the race.
Backstay → The word is formed from "back" (from Old English "bæc", meaning the rear or behind) and "stay" (from Old French "estai", meaning to support or prop). A backstay refers to a support that is positioned at the rear of a structure, particularly in sailing, where it helps to stabilize the mast.
Think of something that supports from the 'back' — 'back' means the rear, and 'stay' means to support. A backstay is a support that stabilizes from behind.
