the word "wolfish" is a transparent english compound formed by appending the native adjectival suffix "-ish" to the noun "wolf". the noun "wolf" itself has a deep indo-european heritage, traceable to the reconstructed root "wĺ̥kʷos", which yielded cognates across ancient languages, including latin "lupus" and greek "lykos". the suffix "-ish", originating from proto-germanic "-iskaz", is a highly productive element for forming descriptive adjectives. thus, "wolfish" literally means "having the nature or qualities of a wolf," a meaning that has evolved from the literal description of resemblance to encompass metaphorical traits like ferocity, greed, and predatory instinct associated with the animal's behavior.
