English grammar is the set of rules that govern the structure of words, phrases, clauses, and sentences in the English language.
It includes the rules for constructing and using nouns, verbs, adjectives, adverbs, pronouns, and other parts of speech, as well as the rules for forming and punctuating sentences.
English grammar is based on the principles of syntax, which is the study of the rules for constructing sentences in a language. These rules vary among languages and can be complex, but learning and understanding them is essential for effective communication in English.
Some of the key concepts in English grammar include parts of speech, verb tenses, subject-verb agreement, and punctuation. To improve your understanding of English grammar, it may be helpful to study a grammar reference book or take a course in English grammar (feel free to contact me). It may also be helpful to practice writing and speaking in English (also feel free to contact me) and to pay attention to the grammar used in published writing and in spoken language.
