A handkerchief (/ˈhæŋkərtʃɪf/; also called a hankie or, historically, a handkercher) is a form of a kerchief or bandanna, typically a hemmed square of thin fabric which can be carried in the pocket or handbag, and which is intended for personal hygiene purposes such as wiping one's hands or face, or blowing one's nose. A handkerchief is also sometimes used as a purely decorative accessory in a suit pocket; it is then called a pocket square. It is also an important accessory in many folk-dances in many regions like the Balkans and the Middle East; an example of a folk-dance using handkerchiefs is Kalamatianos.
