Grammar

In linguistics, grammar is the set of structural rules governing the composition of clauses, phrases, and words in any given natural language. The term refers also to the study of such rules, and this field includes morphology, syntax, and phonology, often complemented by phonetics, semantics, and pragmatics.

English grammar is the structure of expressions in the English language. This includes the structure of words, phrases, clauses and sentences. There are historical, social, cultural and regional variations of English. For instance, Old English uses thee and thou instead of you, and thy instead of your. Different variations of English may have different spellings or may use different words for the same thing. For example, in British (or the Queen's) English, a lift is what is called, in American English, an elevator. In American English, lift is a verb meaning "to raise up".
