IPA: //ˈfɔːrɪsteɪseɪl//
KK: /ˈfɔːrɪsteɪseɪl/
A triangular sail that is attached to the forestay of a sailing vessel, typically used to help with navigation and control of the boat.
The sailor adjusted the forestaysail to catch the wind more effectively.
Forestaysail → It is formed from "fore" (from Old English "foran", meaning in front) and "stay" (from Old English "stǣġ", meaning a support or stay) and "sail" (from Old English "sægl", meaning a sail). The word refers to a sail that is supported by a stay in the front part of a ship.
Think of a sail that is supported ('stay') in the front ('fore') of a ship — that's what a forestaysail is.
