Etymology
Origin of oily
Explanation
Oily things are greasy, slippery, or covered with oil — think a bowl of oily pasta or the oily garage floor after you've been tinkering with your motorcycle's engine. Anything containing oil, covered in oil, or resembling oil is oily. A batch of muffins might taste weirdly oily when you use too much butter, and the rags lying around a car repair shop are mostly black and oily. Your brother's hair will probably be pretty oily after he refuses to wash it for a month. Since the sixteenth century, oily has also had the figurative meaning of "insincerely flattering or slick," like an oily car salesman.
