Role of Phonemes

Role of Phonemes. Theoretically, the spelling of phonemes, the simplest sound elements used to distinguish one word from another, should indicate precisely the sound characteristics of the language.

For example, in English, at contains two phonemes, mat three, and mast four. Very frequently, however, the spelling of English words does not conform to the number of phonemes. Enough, for example, which has four phonemes enuf, is spelled with six letters, as is breath, which also has four phonemes breu and six letters. See Phonetics. The main vowel phonemes in English include those represented by the italicized letters in the following words bit, beat, bet, bate, bat, but, botany, bought, boat, boot, book, and burr. These phonemes are distinguished from one another by the position of articulation in the mouth.

Four vowel sounds, or complex nuclei, of English are diphthongs formed by gliding from a low position of articulation to a higher one. These diphthongs are the i of bite a glide from o of botany to ea of beat, the ou of bout from o of botany to oo of boot, the oy of boy from ou of bought to ea of beat, and the u of butte from ea of beat to oo of boot. The exact starting point and ending point of the glide varies within the English-speaking world. 5.Stress, Pitches, and Juncture Other means to phonemic differentiation in English, apart from the pronunciation of distinct vowels and consonants, are stress, pitch, and juncture.

Stress is the sound difference achieved by pronouncing one syllable more forcefully than another, for example, the difference between record noun and re cord verb. Pitch is, for example, the difference between the pronunciation of John and John Juncture or disjuncture of words causes such differences in sound as that created by the pronunciation of blackbird one word and black bird two words.

English employs four degrees of stress and four kinds of juncture for differentiating words and phrases. 6.Inflection Modern English is a relatively uninflected language. Nouns have separate endings only in the possessive case and the plural number.

Verbs have both a strong conjugation shown in older words with internal vowel change, for example, sing, sang, sung, and a weak conjugation with dental suffixes indicating past tense, as in play, played. The latter is the predominant type. Only 66 verbs of the strong type are in use newer verbs invariably follow the weak pattern. The third person singular has an -s ending, as in does. The structure of English verbs is thus fairly simple, compared with that of verbs in similar languages, and includes only a few other endings, such as -ing or -en but verb structure does involve the use of numerous auxiliaries such as have, can, may, or must. Monosyllabic and some disyllabic adjectives are inflected for degree of comparison, such as larger or happiest other adjectives express the same distinction by compounding with more and most. Pronouns, the most heavily inflected parts of speech in English, have objective case forms, such as me or her, in addition to the nominative I, he, we and possessive forms my, his, hers, our. 7.Parts of Speech Although many grammarians still cling to the Graeco-Latin tradition of dividing words into eight parts of speech, efforts have recently been made to reclassify English words on a different basis.

The American linguist Charles Carpenter Fries, in his work The Structure of English 1952, divided most English words into four great form classes that generally correspond to the noun, verb, adjective, and adverb in the standard classification.

He classified 154 other words as function words, or words that connect the main words of a sentence and show their relations to one another.

In the standard classification, many of these function words are considered pronouns, prepositions, and conjunctions others are considered adverbs, adjectives, or verbs. 8.
