English grammar

English grammar is the way in which meanings are encoded into wordings in the English language. This includes the structure of words, phrases, clauses, and sentences, right up to the structure of whole texts. English grammar is the way in which meanings are encoded into wordings in the English language. This includes the structure of words, phrases, clauses, and sentences, right up to the structure of whole texts. There are historical, social, cultural and regional variations of English. Divergences from the grammar described here occur in some dialects. This article describes a generalized present-day Standard English – a form of speech and writing used in public discourse, including broadcasting, education, entertainment, government, and news, over a range of registers from formal to informal. There are differences in grammar between the standard forms of British, American, and Australian English, although these are more minor than differences in vocabulary and pronunciation. Modern English has largely abandoned the inflectional case system of Indo-European in favor of analytic constructions. The personal pronouns retain morphological case more strongly than any other word class (a remnant of the more extensive Germanic case system of Old English). For other pronouns, and all nouns, adjectives, and articles, grammatical function is indicated only by word order, by prepositions, and by the 'Saxon genitive or English possessive' (-'s). Eight 'word classes' or 'parts of speech' are commonly distinguished in English: nouns, determiners, pronouns, verbs, adjectives, adverbs, prepositions, and conjunctions. Nouns form the largest word class, and verbs the second-largest. Unlike many Indo-European languages, English nouns do not have grammatical gender. Nouns, verbs, adjectives, and adverbs form 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 others are considered to be 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 words are not generally marked for word class. It is not usually possible to tell from the form of a word which class it belongs to except, to some extent, in the case of words with inflectional endings or derivational suffixes. On the other hand, most words belong to more than one word class. For example, run can serve as either a verb or a noun (these are regarded as two different lexemes). Lexemes may be inflected to express different grammatical categories. The lexeme run has the forms runs, ran, runny, runner, and running. Words in one class can sometimes be derived from those in another. This has the potential to give rise to new words. The noun aerobics has recently given rise to the adjective aerobicized. Words combine to form phrases. A phrase typically serves the same function as a word from some particular word class. For example, my very good friend Peter is a phrase that can be used in a sentence as if it were a noun, and is therefore called a noun phrase. Similarly, adjectival phrases and adverbial phrases function as if they were adjectives or adverbs, but with other types of phrases the terminology has different implications. For example, a verb phrase consists of a verb together with any objects and other dependents; a prepositional phrase consists of a preposition and its complement (and is therefore usually a type of adverbial phrase); and a determiner phrase is a type of noun phrase containing a determiner. There are many common suffixes used to form nouns from other nouns or from other types of words, such as -age (as in shrinkage), -hood (as in sisterhood), and so on, although many nouns are base forms not containing any such suffix (such as cat, grass, France). Nouns are also often created by conversion of verbs or adjectives, as with the words talk and reading (a boring talk, the assigned reading). Nouns are sometimes classified semantically (by their meanings) as proper nouns and common nouns (Cyrus, China vs. frog, milk) or as concrete nouns and abstract nouns (book, laptop vs. heat, prejudice). A grammatical distinction is often made between count (countable) nouns such as clock and city, and non-count (uncountable) nouns such as milk and decor. Some nouns can function both as countable and as uncountable such as the word 'wine' (This is a good wine, I prefer red wine).
