Word Classes and Phrases
There are eight word classes, or parts of speech, that are distinguished in English: nouns, determiners, pronouns, verbs, adjectives, adverbs, prepositions, and conjunctions. (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.
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), the adverb 24/7 (as in I am working on it 24/7), and similar relatively new words. The others are regarded as closed classes. For example, it is rare for a new pronoun to be admitted to 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, some 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, 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, adjective phrases and adverb 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 together with its complement (and is therefore usually a type of adverb phrase); and a determiner phrase is a type of noun phrase containing a determiner.

Famous quotes containing the words word, classes and/or phrases:
“It was modesty that invented the word “philosopher” in Greece and left the magnificent overweening presumption in calling oneself wise to the actors of the spirit—the modesty of such monsters of pride and sovereignty as Pythagoras, as Plato.”
—Friedrich Nietzsche (1844–1900)
“I have no doubt but that the misery of the lower classes will be found to abate whenever the Government assumes a freer aspect and the laws favor a subdivision of Property.”
—James Madison (1751–1836)
“I know those little phrases that seem so innocuous and, once you let them in, pollute the whole of speech. Nothing is more real than nothing. They rise up out of the pit and know no rest until they drag you down into its dark.”
—Samuel Beckett (1906–1989)
