About word size in computers?

I just learnt that most computers today have word sizes of 32 or 64 bits. Why, then, do we need to declare an integer as "short" or "long". The end result is that the short int will anyway be converted to a longer word size, since the processor can only handle 32 bit words.

Please clarify.

    Because the standard that defined ANSI C / C++ says short means 16-bit (at least). In Java and Windows it's 16-bit for sure.

    Word size is dependent on CPU, but language variable type integer / short / long is not dependent.
