There are certain English words which have to be pronounced differently depending on their function. If ''use'' is used as a noun, then it will be pronounced as ''u-ce'' where ''-ce'' sounds as in juice. On the other hand if ''use'' is used as a verb, then it will be pronounced as ''u-zed'' where ''-zed'' sounds as in oozed. Fortunately there are few words of this type in English language.
Once someone told me in Japanese and Chinese there are a lot of words which are pronounced differently to mean different things. This is in contrast with the different pronunciation of the same word in English language, where different pronunciations merely signify different function of the word. Am I correct?
