2. Morphemic structure of a word

morpheme is the elementary meaningful part of the word. There are the following distributional morpheme types which classification is arranged in the form of oppositional pairs of immediate correlation.

morpheme

• on the basis of the degree of self-dependence

free (blamed, beautifully)

bound (blamed, beautifully)

• on the basis of formal presentation

overt (clock + s)

covert (clock + zero morpheme of singular number)

• on the basis of segmental relation

segmental (root and affixes)

supra-segmental (intonation contours, accents, pauses )

• on the basis of grammatical alternation

additive (outer grammatical suffixes

replacive (the root phonemes of grammatical interchange: dr-i-ve - dr-o-ve - dr-i-ven )

• on the basis of linear characteristic

continuous (is working, has driven)

discontinuous (work, drives)‏

• on the basis ofmeaningfulness

meaningful (root and affixes)‏

empty (connecting morphemes: child-r-en)‏

3.Lexico-grammatical classes of words

The traditional term “parts of speech” was developed in Ancient Greek linguistics and reflects the fact that at that time there was no distinction between language as a system and speech, between the word as a part of an utterance and the word as a part of lexis. The term “parts of speech” is accepted by modern linguistics as a conventional, or “non-explanatory” term (“name-term”) to denote the lexico-grammatical classes of words correlating with each other in the general system of language on the basis of their grammatically relevant properties.

There are three types of grammatically relevant properties of words that differentiate classes of words called “parts of speech”: semantic, formal and functional properties.

The semantic criterion refers to the generalized semantic properties common to the whole class of words, e.g.: the generalized (or, categorial) meaning of nouns is “thingness”, of verbs process, of adjectives substantive property, of adverbs non-substantive property. The formal criterion embraces the formal features (word-building and word-changing) that are characteristic for a particular part of speech. Combinability is also a relevant formal feature for each particular part of speech; for example, verbs can be modified by adverbs, while nouns cannot (except in specific contexts). Classifications in general may be based either on one criterion (such classifications are called homogeneous, or monodifferential), or on a combination of several criteria (such classifications are called heterogeneous, or polydifferential). The traditional classification of parts of speech is polydifferential (heterogeneous); it is based on the combination of all the three criteria mentioned above: ‘meaning – form – function’.

Traditionally, all parts of speech are subdivided on the upper level of classification into notional words and functional words. Notional words, which traditionally include nouns, verbs, adjectives, adverbs, pronouns and numerals, have complete nominative meanings, are in most cases changeable and fulfill self-dependent syntactic functions in the sentence. The noun, for example, as a part of speech, is traditionally characterized by 1) the categorial meaning of substance (“thingness”), 2) a specific set of word-building affixes, the grammatical categories of number, case and article determination, prepositional connections and modification by an adjective, and 3) the substantive functions of subject, object or predicative in the sentence. In the same way, all the other notional parts of speech are described. Functional words, which include conjunctions, prepositions, articles, interjections, particles, and modal words, have incomplete nominative value, are unchangeable and fulfill mediatory, constructional syntactic functions.
