Parasiticus is a Latin adjective meaning "parasitic" or "pertaining to a parasite". It is derived from the Latin noun parasītus, which originates from the Ancient Greek παράσῑτος (parásītos), meaning "one who eats at the table of another". The term is built from para- ("beside") and sitos ("food/grain").
