Briefly put, in linguistics, syntax is the study of the rules that govern the structure of sentences, and which determine their relative grammaticality.
The term syntax can also be used to refer to these rules themselves, as in "the syntax of a language". Modern research in syntax attempts to describe languages in terms of such rules, and, for many practitioners, to find general rules that apply to all languages. Since the field of syntax attempts to explain grammaticality judgments, and not provide them, it is unconcerned with linguistic prescription.
Semantics refers to aspects of meaning, as expressed in language or other systems of signs. Semantics contrasts with syntax, which is the study of the structure of sign systems (focusing on the form, not meaning). By the usual convention that calls a study or a theory by the name of its subject matter, semantics may also denote the theoretical study of meaning in systems of signs.
