IPA: /ˈɡaɪlaɪn/
KK: /ˈɡaɪlaɪn/
A rope or cable that is used to keep something stable or in place, often used to support a structure like a tent or a mast.
The campers secured the tent with a guyline to prevent it from blowing away in the wind.
The word 'guyline' originates from the term 'guy' (from Middle French *guie*, meaning a rope or cord) and 'line' (from Old English *līne*, meaning a string or cord). A guyline is a rope or cord used to stabilize a structure, particularly in tents or masts.
Think of a 'rope' ('guy') that helps 'stabilize' ('line') something, like a tent or a mast, to remember that a guyline is used for support.
