Word Structure: X → Y*+X [Question : Which categories are allowed as Y and X?] In Chinese, at least nouns can have "compound structure", apparently according to rules like Noun → Noun+Noun (e.g., yīng yŭ: England language; gāng qīn jiā: piano player). Question: Is this possible with adjectives and verbs, too? In particular, are there Chinese compound adjectives STRUCTURALLY equivalent to English "cost-efficient", "love-sick", or "tax-free" and verbs structurally equivalent to English "spoon-feed", "hand-wave", or "peer-review" (Note that I am not talking about the usual Chinese type V+N, as in "chi1 fan1" , which is NOT a compound, since "guò" may occur between "chi1" and "fàn", as in "Zuo2 tian1, wo3 zài zhè ge fàn guan3 chi1 guo wan3 fan2")? Related question: Is it possible to build compounds recursively, i.e., does Chinese allow structures exactly like "[jazz+piano]+player", where "jazz+piano" is a compound-like structure inside a larger compound-like structure? Or is it necessary to introduce "de" or some other particle between a noun and the next? Thank you!
