The study of syntax is important to understand language acquisition. Research and explain what the subject, verb, and object are, with some examples. Also explain what a phrase, clause, and sentence are, in brief, with examples of each. And list and briefly explain the parts of speech in English (nouns, adjectives [including articles and determiners], pronouns, lexical and auxiliary verbs, adverbs, prepositions, conjunctions, and interjections) and provide examples of each.
