23.Speak on: Classification of Morphemes according to m.Y.Blokh p.P. 27-37

In linguistics, a morpheme is the smallest grammatical unit in a language. The field of study dedicated to morphemes is called morphology. A morpheme is not identical to a word, and the principal difference between the two is that a morphememay or may not stand alone, whereas a word, by definition, is freestanding. Every word comprises one or more morphemes. Classification of morphemes

[edit]Free vs. bound

Every morpheme can be classified as either free or bound. These categories are mutually exclusive, and as such, a given morpheme will belong to exactly one of them.

  • Free morphemes can function independently as words (e.g. towndog) and can appear with other lexemes (e.g. town hall,doghouse).

  • Bound morphemes appear only as parts of words, always in conjunction with a root and sometimes with other bound morphemes. For example, un- appears only accompanied by other morphemes to form a word. Most bound morphemes in English are affixes, particularly prefixes and suffixes, examples of suffixes are: tion, ation, ible, ing etc.. Bound morphemes that are not affixes are called cranberry morphemes.

Bound morphemes can be further classified as derivational or inflectional.

  • Derivational morphemes, when combined with a root, change either the semantic meaning or part of speech of the affected word. For example, in the word happiness, the addition of the bound morpheme -ness to the root happy changes the word from an adjective (happy) to a noun (happiness). In the word unkindun- functions as a derivational morpheme, for it inverts the meaning of the word formed by the root kind.

  • Inflectional morphemes modify a verb's tense or a noun's number without affecting the word's meaning or class. Examples of applying inflectional morphemes to words are adding -s to the root dog to form dogs and adding -ed to wait to form waited.

[edit]Allomorphs

Allomorphs are variants of a morpheme that differ in pronunciation but are semantically identical. For example, in English, the pluralmarker -(e)s of regular nouns can be pronounced /-z/, /-s/, or /-ɨz/, depending on the final sound of the noun's singular form.

24. The Grammatical classes of the word.

The words of language, depending on various formal and semantic features, are divided into grammatically relevant sets or classes. The traditional grammatical classes or words are called “parts of speech”. “Parts of speech” are the basic types of words that English has. Most grammar books say that there are eight parts of speech: nouns, verbs, adjectives, adverbs, pronouns, conjunctions, prepositions and interjections. We will add one more type: articles.

It is important to be able to recognize and identify the different types of words in English, so that you can understand grammar explanations and use the right word form in the right place. Here is a brief explanation of what the parts of speech are:

Noun. A noun is a naming word. It names a person, place, thing, idea, living creature, quality, or action. Examples: cowboy, theatre, box, thought, tree, kindness, arrival

Verb. A verb is a word which describes an action (doing something) or a state (being something). Examples: walk, talk, think, believe, live, like, want

Adjective. An adjective is a word that describes a noun. It tells you something about the noun. Examples: big, yellow, thin, amazing, beautiful, quick, important

Adverb. An adverb is a word which usually describes a verb. It tells you how something is done. It may also tell you when or where something happened. Examples: slowly, intelligently, well, yesterday, tomorrow, here, everywhere

Pronoun. A pronoun is used instead of a noun, to avoid repeating the noun. Examples: I, you, he, she, it, we, they

Conjunction. A conjunction joins two words, phrases or sentences together. Examples: but, so, and, because, or

Preposition. A preposition usually comes before a noun, pronoun or noun phrase. It joins the noun to some other part of the sentence. Examples: on, in, by, with, under, through, at

Interjection. An interjection is an unusual kind of word, because it often stands alone. Interjections are words which express emotion or surprise, and they are usually followed by exclamation marks. Examples: Ouch!, Hello!, Hurray!, Oh no!, Ha!

Article. An article is used to introduce a noun.Examples: the, a, an
