IPA: /ˈjɑːrdɑːrm/
KK: /ˈjɑrdˌɑrm/
The end of a horizontal pole on a ship that supports the sails.
The crew adjusted the sails attached to the yardarm to catch the wind.
Yardarm is formed from "yard" (from Old English *geard*, meaning an enclosed area or a rod) and "arm" (from Old English *earm*, meaning a limb or branch). The term refers to the horizontal spar on a sailing ship that extends from the mast, resembling an arm extending outwards.
Think of a 'yard' as a rod or area and an 'arm' as a limb extending out — together, they describe the part of a ship that reaches out like an arm.
