​HAIK (an Arabic word, from hak, to weave), a piece of cloth, usually of coarse hand-woven wool, worn by Arabs, Moors and other Mahommedan peoples. It is generally 6 to 61/2 yds. long, and about 2 broad. It is either striped or plain, and is worn equally by both sexes, usually as an outer covering; but it is often the only garment of the poorer classes. By women the “haik” is arranged to cover the head and, in the presence of men, is held so as to conceal the face. A thin “haik” of silk, like a veil, is used by brides at their marriage.
