A notable feature of language is the use of the same word to communicate different meanings. The first example that comes to mind in English is still. I am aware of at least three meanings (1) when something is motionless or at rest, (2) apparatus used to distill alcohol, and (3) the adverb still which means 'as yet' or 'up to this time' (for example, 'are you still there?').
