And we use compound to label other types of multiword lexemes, with headedness according to the language and/or compound type.
compound is used for any kind of X 0 compounding: noun compounds (e.g., phone book), but also verb and adjective compounds that are more common in other languages (such as Persian or Japanese light verb constructions); for numbers (e.g., three thousand books gives compound(thousand, three)); for particles of phrasal verbs (e.g., put up: compound(put, up)).
