IPA: /ˌbæl.əˈklɑː.və/
KK: /bæləˈklɑːvə/
A warm, knitted garment that covers the head, face, and neck, often used for protection against cold weather.
He wore a balaclava to keep warm while skiing in the mountains.
Balaclava originates from the name of a town in Crimea, Balaklava, where a type of knitted headgear was first used by British soldiers during the Crimean War. The term refers specifically to a garment that covers the head, face, and neck, leaving only the eyes, mouth, and sometimes the nose exposed.
Imagine a soldier in the cold, wearing a knitted cap that covers most of their face and neck — that's what a balaclava is, named after the place where it became popular.
