Functions of stress.

The nature of stress in different languages is different. According to A.Gimson, the effect of prominence is achieved by four factors: force, tone, length and vowel colour. The dynamic stress implies greater force with which the syllable is pronounced. It means that the greater muscular energy is produced by the speaker. European languages such as English, German, French, Russian posses dynamic word stress. The musical word stress is observed in Chinese, Japanese, and Vietnamese. It is effected by the variations of voice pitch in relation to the next syllables. The English linguists (D. Crystal, A. Gimson) agree that in English word stress is a complex phenomenon, marked by the variations in force, pitch, quantity and quality. The dynamic and the tonic features of English word stress prevail over the others. The accent is also influenced by the vowel length and quality. The vowel of the stressed syllable is never reduced and it is longer than in the unstressed one. Languages are also differentiated according to the place of word stress. It may be fixed and free. In languages with a fixed stress its place is on the particular syllable. In French the stress falls on the last syllable, in Finnish and Czech it is fixed on the first one, in Polish on the last but one. The word stress in English is not only free but it may be shifting, performing the semantic function of differentiating lexical units. There are as many degrees of stress in a word as there are syllables. The American scientists B. Blokh and G.Trager ind four degrees of word stress: primary, secondary, tertiary and weak stress. The English word stress is limited by two tendencies: Recessive and Rhythmical due to their origin. In Germanic languages the word stress originally fell on the initial syllable or the second syllable, the root syllable in the English words with prefixes. This tendency was called Recessive. Most English words of Anglo-Saxon origin as well as the French borrowings are subjected to this tendency. (mother, daughter, brother, swallow).; in French borrowings( reason, colour, restaurant). It also marks English words with prefixes (foresee, begin, withdraw, apart). A great number of words of A.-S. origin are monosyllabic or disyllabic, they tend to alternate in the flow of speech, e. g. I don’t believe he is right. The alternation of stressed and unstressed syllables gave birth to the Rhythmical tendency in the present-day English which caused the appearance of the secondary stress in the multisyllabic French borrowings (revolution, organization, assimilation). It also explains the placement of primary stress on the third syllable from the end in three- and four- syllable words (cinema, articulate, situates). The interrelation of both – the recessive and the rhythmical tendencies is traced in the process of accentual assimilation of the French – borrowed word –personal; (personal –personal-personal). Nowadays we see a great number of variations in the accentual structure of many English words with a strong influence of rhythmical tendency: ‘ hospitable- hos’pitable, aristocrat- aristocrat. The numerous variations of English word stress are systematized in the typology of accentual structure of English words worked out by Torsuev G. P. He distinguishes more than 100 stress patterns, which he grouped into 11 types. The tempo of speech may influence the accentual pattern of words too. Word stress in a language performs 3 functions: 1. It constitutes a word, it organizes the syllables of a word into a language unit having a definite accentual structure, so it performs the constitutive function. 2. Word stress enables a person to identify a succession of syllables as a definite accentual pattern of a word. The function is identificatory. 3. Word stress alone is capable of differentiating the meaning of words or their forms, thus performing its distinctive function. (im’port –‘import, billow-bellow).
