11. Types of word-form derivation in English. Inflectional morphemes, sound alternation, zero morpheme.

1)In the system of the English noun we distinguish the following inflectional morphemes: a) ‘es’, ‘s’, ‘en’ – expressing the idea of plurality. b) apostrophe ‘s’ – expressing the idea of possession

In the sphere of the English adjective the suffixes ‘er’, ‘est’ – are the only inflectional morphemes, expressing the idea of the comparative and superlative degrees of adjectives. 2)The zero morpheme – is characterized by the absence of the inflection, but this absence is meaningful as it presents the idea of singularity. Let’s consider some examples – girl – girls, child – children, woman – women. The first column of opposition (girl, child, woman) is characterized by the zero morpheme, expressing the idea of singularity. 3) Sound alternation can change the grammatical meaning of the word in following cases: 1. In irregular words (come – came, meet- met, see- saw, build- built); 2. In the formation of the plural (woman – women, man – men, foot – feet, tooth- teeth, mouse – mice, goose – geese, louse – lice. ). 3. In changing the stress. Unless we learn the right stress of the words, we can’t refer them to a definite part of speech. The change of stress can bring about the change in the grammatical meaning of the word – for example – Export (noun) – expOrt (verb), Import (noun) – impOrt (verb);

4.The change of intonation can also play a certain grammatical role as it can change the type of the sentence.(for ex. “He has nothing to say” – it is said with a falling tone, that’s a statement; ‘He has nothing to say’ – it is said with a rising tone, that’s why it expresses doubt. This type of sentences is called semi-interrogative.)

10) The basic morphological notions: word-morpheme, morph, allomorph.

The basic morphological notions are word and morpheme. Word is the smallest naming unit. It’s a sequence of human sounds, conveying a certain notion. Morphemes are the smallest meaningful units, into which a word form can be divided.

The word-form ‘workers’ can be divided into 3 morphemes: ‘work’ expressing the basic lexical meaning of the word; ’er” expressing the doer of the action; ‘s’ is a morpheme, expressing the idea of plurality.

In order to understand what an allomorph is, we will form an opposition – girl – girls, child- children, woman – women. Here morphemes ‘s, en, e’ have the same grammatical meaning, because they express plurality. They are allomorphs, that is variants of a morpheme of plurality.

Allomorph is a variant of a morpheme which occurs in certain environments.

Thus, the morpheme is a group of one or more allomorphs. We can distinguish root morphemes and affixal morphemes.

13) Parts of speech. The notion of parts of speech. Difficulties of the problem. Criteria applied in discriminating parts of speech: meaning, form and function.

The meaning of the word, its form, the place in the sentence and its combinability can be of help in classifying words as belonging to a certain part of speech. Parts of speech are lexico-grammatical classes of words, which are united on the basis of a general meaning, common to the whole class (thingness, action, property) and on the basis of their morphological and syntactical character.

The representatives of traditional grammar distinguish 7 or 8 parts of speech. They didn’t distinguish between notional and structural parts of speech. The majority of Soviet linguists point out 13 parts of speech. For example, Professor Smirnitsky, Ganshina and Vasilevskaya distinguish 3 classes of words: 1) Notional or significant words – they have independent meaning and perform a certain function in the sentence. They are 6: noun, pronoun, adjective, numeral, verb and adverb. 2) Form words, which are subdivided into 2 groups – connective form words (prepositions and conjunctions) and determinatives ( articles and particles). 3) It includes independent elements which do not enter into the structure of the sentence as its parts. They are 3 in number – interjections, yes/no words, parenthetical words.
