Some semantic checks can be done by the compiler - particularly type checking - so I agree that compilers don't only find syntax errors, but Chris only said "won't find all That didn't help me understand anything. –gsingh2011 Oct 13 '11 at 21:46 +1 for asking this question.

As soon as one tries to express semantic in form of data, it becomes syntax. Humans do understand syntax too, and computers understand some kinds of semantics. –CesarGon Oct 12 '11 at 12:17 4 Plainly wrong.
