Type of Grammar
The second type of grammar is the traditional grammar which concerns the parts of speech; this means labelling the parts with names such as nouns, verbs, adjectives, etc. and givingrules that explain how they may or may not be combined. The third type is called structural grammar which is based on the concept of phrase structure that show how words go together in a sentence and some do not. The phrase structure is usually presented in tree diagrams that show how words build up into phrases and phrases buildup into sentences describing how these elements fit together in an overall structure. However, the fourth type is the one in which second language acquisition relies on; this type is called grammatical competence which refers to the knowledge of language that the speaker possesses in the mind.
