From the Greek name Φιλανδρος (Philandros)
meaning "friend of man" from Greek φιλος (philos)
"friend" and ανδρος (andros)
"of a man". It was the name of a son of Apollo
with the nymph Acalle. In the 18th century this was coined as a word meaning "to womanize", and the name subsequently dropped out of use.
