1. Usually a beautician or someone who specializes in giving treatment of the fingernails; including, shaping and polishing: There are people who go to manicurists regularly for treatment of their fingernails and, sometimes, even for other conditions of their hands.

Someone once wrote that we should remember that only manicurists are literally making money "hand over fists".

2. Etymology: "a person who professionally treats hands and fingernails" which came from French manicure; literally, "the care of the hands"; from Latin manus, "hand" + cura, "care, treatment".
