Re: Semantic? Syntax?

For any reasonable language L (formal, programming, or even natural)
syntax of L is just description of 
which expressions are belong to L, i.e. what is the <<correct
expression>> (formula, sentence, programm, etc.)
of L, while semantics describes a <<meaning>> (whatever it means for any
particular language).
