1. Paradigmatic (or selectional) and syntagmatic (or combinatory) axes of linguistic structure represent the way vocabulary is organised.
Syntagmatic relations define the word-meaning in the flow of speech in various contexts.
Paradigmatic relations define the word-meaning through its interrelation with other members within one of the subgroups of vocabulary units.
On the syntagmatic axis the word-meaning is dependent on different types of contexts. Linguistic context is the minimal stretch of speech necessary to determine individual meanings.
Linguistic (verbal) contexts comprise lexical and grammatical contexts and are opposed to extra-linguistic (non-verbal) contexts. In extra-linguistic contexts the meaning of the word is determined not only by linguistic factors but also by the actual speech situation in which the word is used.
The semantic structure of polysemantic words is not homogeneous as far as the status of individual meanings is concerned. A certain meaning (or meanings) is representative of the word taken in isolation, others are perceived only in various contexts.
Classification of vocabulary into thematic groups is based on common contextual associations. Contextual associations are formed as a result of regular co-occurrence of words in similar, repeatedly used contexts within the framework of sentences.
The main criterion underlying semantic classification of vocabulary items on the paradigmatic axis is the type of meaning relationship between words.
The criterion of common concept serves to classify words into semantic fields and lexico-semantic groups.
62 Semantic relationship of inclusion is the main feature of hyponymic hierarchical structure Semantic similarity and semantic contrast is the type of relationship which underlies the classification of lexical items into synonymic and antonymic series.
Synonymy and antonymy are correlative and sometimes overlapping notions. Synonymous relationship of the denotational meaning is in many cases combined with the difference in the connotational (mainly stylistic) component.
It is suggested that the term synonyms should be used to describe words different in sound-form but similar in their denotational meaning (or meanings) and interchangeable at least in some contexts.
The term antоnуms is to be applied to words different in sound-form characterised by different types of semantic contrast of the denotational meaning and interchangeable at least in some contexts.
111. Word-Groups and Phraseological Units
Words put together to form lexical units make phrases or word-groups. It will be recalled that lexicology deals with words, word-forming morphemes and word-groups. We assume that the word is the basic lexical unit.1 The smallest two-facet unit to be found within the word is the morpheme which is studied on the morphological level of analysis. The largest two-facet lexical unit comprising more than one word is the word-group observed on the syntagmatic level of analysis of the various ways words are joined together to make up single self-contained lexical units.
The degree of structural and semantic cohesion of word-groups may vary. Some word-groups, e.g. at least, point of view, by means of, take place, seem to be functionally and semantically inseparable. Such word-groups are usually described as set-phrases, word-equivalents or phraseological units and are traditionally regarded as the subject matter of the branch of lexicological science that studies phraseology.
The component members in other word-groups, e.g. a week ago, man of wisdom, take lessons, kind to people, seem to possess greater semantic and structural independence. Word-groups of this type are defined as free or variable word-groups or phrases and are habitually studied in syntax.
Here, however, we proceed from the assumption that before touching on the problem of phraseology it is essential to briefly outline the features common to various types of word-groups viewed as self-contained lexical units irrespective of the degree of structural and semantic cohesion of the component words.
SOME BASIC FEATURES OF WORD-GROUPS
To get a better insight into the essentials of structure and meaning of word-groups we must begin with a brief survey of the main factors active in uniting words into word-groups. The two main linguistic factors to be considered in this connection are the lexical and the grammatical valency of words.
