The Basic Feature of Word-Groups (Lexical Valency, Grammatical Valency)
Structure and Meaning in Word-Groups.
Words put together to form lexical units make phrases or word-groups. Lexicology deals with words, word-forming morphemes and word-groups we assume that the word is the basic lexical unit. The smallest morpheme which is studied on the morphological level of analysis.
The largest two-facet lexical unit comprising more than one word is the word-groups 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 [k u`hi:z n] of word-groups may vary. Some word-groups, e.g. at least, point of view, by means of, take place, seem to be usually described as set-phrases, word-equivalent or phraseological units and are traditionally regarded as the subject matter of the branch of lexical science, that studies phraseology.
The component members in other word-groups, e.g. ‘a week ago, man of wisdom, take lesson, kind to people, seem to possess, greater semantic and structural independence. Word-groups of this type are defined as free on variable word-groups or phrases and are habitually studied in syntax.
