English grammar for beginners-part 1  

English grammar is the set of structural rules of the English language. This includes the structure of words, phrases, clauses, sentences, and whole texts.

A word is a basic element of language that carries meaning, can be used on its own, and is uninterruptible.

In grammar, a phrase—called an expression in some contexts—is a group of one or more words acting as a grammatical unit. For instance, the English expression "the very happy squirrel" is a noun phrase which contains the adjective phrase "very happy". Phrases can consist of a single word or a complete sentence. In theoretical linguistics, phrases are often analyzed as units of syntactic structure such as a constituent. There is a difference between the common use of the term phrase and its technical use in linguistics. In common usage, a phrase is usually a group of words with some special idiomatic meaning or other significance, such as "all rights reserved", "economical with the truth", or "kick the bucket". It may be a euphemism, a saying or proverb, a fixed expression, a figure of speech, etc. In linguistics, these are known as phrasemes.

In language, a clause is a constituent or phrase that comprises a semantic predicand (expressed or not) and a semantic predicate. A typical clause consists of a subject and a syntactic predicate,the latter typically a verb phrase composed of a verb with or without any objects and other modifiers. However, the subject is sometimes unexpressed if it is easily deducible from the context, especially in null-subject languages but also in other languages, including instances of the imperative mood in English.

A complete simple sentence contains a single clause with a finite verb. Complex sentences contain at least one clause subordinated to (dependent on) an independent clause (one that could stand alone as a simple sentence), which may be co-ordinated with other independents with or without dependents. Some dependent clauses are non-finite, i.e. they do not contain any element/verb marking a specific tense.

In linguistics and grammar, a sentence is a linguistic expression, such as the English example "The quick brown fox jumps over the lazy dog." In traditional grammar, it is typically defined as a string of words that expresses a complete thought, or as a unit consisting of a subject and predicate.A sentence can include words grouped meaningfully to express a statement, question, exclamation, request, command, or suggestion.

Word classes and phrases

Nouns, verbs, adjectives, and adverbs are open classes – word classes that readily accept new members, such as the noun celebutante (a celebrity who frequents the fashion circles), and other similar relatively new words. The rest are closed classes; for example, it is rare for a new pronoun to enter the language. Determiners, traditionally classified along with adjectives, have not always been regarded as a separate part of speech. Interjections are another word class, but these are not described here as they do not form part of the clause and sentence structure of the language.

English nouns form the largest category of words in English, both in the number of different words and how often they are used in typical texts. The three main categories of English nouns are common nouns, proper nouns, and pronouns.

Verbs constitute one of the main parts of speech (word classes) in the English language. Like other types of words in the language, English verbs are not heavily inflected. Most combinations of tense, aspect, mood and voice are expressed periphrastically, using constructions with auxiliary verbs.
