Welcome to EF, Kseeker. You should be careful to distinguish form from function. I myself like to write it out like the following, to avoid any confusion by the reader: The university guard -- noun used as adjective The Chinese Embassy -- adjective used as adjective (the noun is China , unless you are speaking of the people) The Japanese economics professor -- noun used as adjective cf: Running is a healthy hobby -- verb used as noun The rich get richer -- adjective used as noun
