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. Divergences from the grammar occur in some dialects of English. There are certain differences in grammar between the standard forms of British English, American English and Australian English, although these are inconspicuous compared with the lexical and pronunciation differences.
The word "grammar" has many meanings. For some people, grammar specifies the "correct" way to speak or write. For others, the word refers to the inflections (the word endings) common in many languages. For still others, the grammar is about how humans organize ideas into words. The word "grammar" means all of those things. But, for us, the word means something quite specific: grammar describes how we choose and arrange our words.
