30. The definition of word-stress. The classification of word-stress according to its relevant features.

Word-stress is connected with the changes of the force of articulation, pitch, colour and length of a vowel in a stressed syllable. So word-stress is based upon four principles – dynamic, musical, qualitative and quantitative. In different languages one of the factors, constituting word-stress is usually more significant than the others and consequently is said to be phonologically relevant. According to the most important feature of word-stress different types of it are distinguished in different languages.

If special prominence in a stressed syllable is achieved mainly through the intensity of articulation, such type of stress is called dynamic or force-stress.

If special prominence in a stressed syllable is achieved mainly through the change of pitch, or musical tone such accent is called musical or tonic.

If special prominence in a stressed syllable is achieved through the changes in the quality of the vowels, which are longer in the stressed syllable than in the unstressed ones, such type of stress is called quantitative.

If special prominence in a stressed syllable is achieved through the changes in the quality of the vowels which are not obscured in the stressed syllables and are rather obscure in the unstressed ones, such type of stress is called qualitative.

Quantitative and qualitative changes do not form independent phonemically distinctive features, so quantitative and qualitative types of word-stress do not exist separately from dynamic stress. They are conditioned by the latter and play subsidiary role in accentuation of syllables.

Musical or tonic stress is characteristic of the Chinese, Japanese, Korean, Vietnamese and other oriental languages as well as some African languages where it distinguishes words, consisting of the same sounds. For example, in Japanese the sequence [hana], pronounced with even tone, means “nose”, pronounced with higher tone on the first syllable, means “beginning” and pronounced with higher tone on the second, syllable means “flower.”

The Scandinavian languages make use of both dynamic stress and tone stress in more or less equal degree.

Word-stress in other European languages, such as English, French, German, Russian is considered to be predominantly dynamic, with other features present but irrelevant. Thus, change of pitch is significant but the direction of pitch is not, since it doesn’t serve for differentiation of words from one another.

31. The definition of word-stress. The classification of word-stress according to its position.

Word-stress is connected with the changes of the force of articulation, pitch, colour and length of a vowel in a stressed syllable.

According to the potion of stress in words, the following types of word-stress are distinguished:

1) fixed word-stress;

2) free word-stress.

In languages with fixed word-stress the main accent invariable falls on a syllable which occupies in all the words of the languages one and the same position in relation to the beginning or end of a word. For instance, in Finnish and Czech word-stress in fixed on the first syllable, in Polish on the one but last syllable. In French the stress falls on the last syllable of the word, pronounced in isolation. Yet when a group of words is uttered, all the words in this group are unstressed, and only the final syllable is stressed, so it led some linguists to the conclusion that French has no word-stress.

In languages with free word-stress (English, Russian, German) the main accent may fall in different words on a syllable in any position in relation to the beginning or end of a word, although the accentual pattern of each word-form remains fixed, in the sense that, its accent is not shifted from one syllable to another in it. So the freedom of stress is not absolute but relative.

Within free word-stress two subtypes are distinguished on morphological ground:

a) constant stress;

b) shifting stress

A constant stress remains on the same morpheme in different grammatical forms of a word or in different derivatives from one and the same root (ex. wonder, wonderful, wonderfully). In a few inflectional grammatical forms that English words have, the stress is always constant (ex. finish, finishes, finishing, finished).

A shifting stress falls on different morphemes in different grammatical forms of a word or in different derivatives from one and the same root. Shifting of word stress may perform semantic function of differentiating lexical units, parts of speech, grammatical forms (ex. ig'nore – 'ignorant, 'contrast – to con'trast, рукá – рýки, домá – дóма, чýдная – чуднáя, мýка – мукá).

Free word-stress presupposes almost complete unpredictability in the incidence of the main accent in different words of the language. In Russian for example, there are no rules determining which syllable of a polysyllabic word bears the main stress, so that the stress of each word and grammatical form of a word has to be learnt individually.
