The full form of "grammar" is the study of rules governing the use of language, particularly syntax, morphology, and semantics.
The eight branches of grammar are morphology (study of word structure), syntax (study of sentence structure), phonology (study of sound patterns), phonetics (study of speech sounds), semantics (study of meaning), pragmatics (study of language use in context), orthography (study of spelling), and punctuation (study of symbols used in writing).
