GRAMMAR = SYNTAX + { MORPHOLOGY + PHONOLOGY + SEMANTICS ( MEANINGS AND PHILOSOPHY ) }
Grammar is the set of rules a language uses to convey meaning. It is one of the fundamental building blocks of language, along with lexicon, or vocabulary. When you use proper grammar, you are following the generally accepted rules of your language.
Elements of grammar include:
Grammar dictates the ways you use words, especially parts of speech. For example, nouns and verbs must agree with each other in your sentence. But, the order of words in that sentence relies on its syntax.
The Greek word syntax means “arrange together.” Syntax has more to do with linguistics than language. Because syntax is a part of grammar, all syntactical rules are also grammar rules. Here are some elements of syntax:
Grammar rules and patterns dictate the ways you use the syntactical parts of a sentence. For example, every sentence must include a subject and a predicate. While there are basic syntactic rules to follow, syntax makes it possible for writers to establish tone by varying the types of sentences in their writing.
