Similar to 'hankie,' a 'hanky' is a colloquial abbreviation for 'handkerchief.' It's a small cloth, usually square, used for wiping one's face, nose, or hands. It's an informal term, common in casual speech. Think of it as a more laid-back way to say 'handkerchief.' Unlike a towel, it's pocket-sized and convenient. It's generally associated with personal hygiene.
