So the separation makes sense. –mouviciel Oct 12 '11 at 11:00 5 @mouviciel, it make sense as an optimisation only - otherwise you'll just have a ValidIdentifier terminal, which could Developers care about design because a good design is about reducing complexity by abstracting complex behaviors and interactions, and different kinds of problems lend themselves to different semantics. A compiler will check your syntax for you (compile-time errors), and derive the semantics from the language rules (mapping the syntax to machine instructions say), but won't find all the semantic This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. http://onlivetalk.com/semantic-error/semantics-error-example.php
Most of the compilers are unable to catch semantic errors though Java does catch some of such errors like type conversion. He refers to the words "syntax" and "semantic" used in data description: so if you stumble upon these words in a specification of some data format, you should better replace both Sometimes some of the information is only useful to someone familiar with the internals of Basis; but we hope that in most cases it will help you find your error. based on wrong assumptions, wrong models, or you've used the wrong formulars, misunderstood the customer, or such.

And sometimes the line between the two can be blurry. http://www.catb.org/~esr/jargon/html/D/DWIM.html A *semantic* error would be something like this: x, y = alist[1:2] when what you actually needed was alist[1:3]. What does "Game of the Year" actually mean? A compiler typically has a lexical analyzer (tokenizer) and a parser as distinct components; both of them deal with syntax. –Keith Thompson Feb 12 '14 at 19:34 add a comment| protected

It doesn't interpret semantics, it interprets syntax.

Semantics is what they mean.

Like left and right? The two are, more or less, analogous. Word order is the basic principal of syntax, those trying to understand what is written use the syntactic cues of word order to help give the sentence structure and meaning. These have to do not with how statements are constructed, but with what they mean.

A syntax error is a failure of the source code to match the language grammar, for example, not having a semicolon where one is required.
One way to understand the distinction is to look at the kinds of errors you get when your program's syntax or semantics is incorrect. These are valid code the compiler understands, but they do not what you, the programmer, intended. Semantic is encoded in syntax.
