A course In Modern English Lexicology

§ 20. Summary and Conclusions connotational components may be found in morphemes of different types. The denotational meaning in affixal morphemes may be rather vague and abstract, the lexical meaning and the part-of-speech meaning tending to blend.
2. It is suggested that in addition to lexical meaning morphemes may contain specific types of meaning: differential, functional and distributional.
3. Differential meaning in morphemes is the semantic component 27
which serves to distinguish one word from other words of similar morphemic structure. Differential and denotational meanings are not mutually exclusive.
4. Functional meaning is the semantic component that serves primarily to refer the word to a certain part of speech.
5. Distributional meaning is the meaning of the pattern of the arrangement of the morphemes making up the word. Distributional meaning is to be found in all words composed of more than one morpheme. It may be the dominant semantic component in words containing morphemes deprived of denotational meaning.
6. Morphological motivation implies a direct connection between the lexical meaning of the component morphemes, the pattern of their arrangement and the meaning of the word. The degree of morphological motivation may be different varying from the extreme of complete motivation to lack of motivation.
7. Phonetical motivation implies a direct connection between the phonetic structure of the word and its meaning. Phonetical motivation is not universally recognised in modern linguistic science.
8. Semantic motivation implies a direct connection between the central and marginal meanings of the word. This connection may be regarded as a metaphoric extension of the central meaning based on the similarity of different classes of referents denoted by the word.
CHANGE Of MEANING
Word-meaning is liable to change in the course of the historical development of language. Changes of lexical meaning may be illustrated by a diachronic semantic analysis of many commonly used English words. The word fond (OE. fond) used to mean ‘foolish’, ‘foolishly credulous’; glad (OE, glaed) had the meaning of ‘bright’, ’shining’ and so on.
Change of meaning has been thoroughly studied and as a matter of fact monopolised the attention of all semanticists whose work up to the early 1930’s was centered almost exclusively on the description and classification of various changes of meaning. Abundant language data can be found in almost all the books dealing with semantics. Here we shall confine the discussion to a brief outline of the problem as it is viewed in modern linguistic science.
To avoid the ensuing confusion of terms and concepts it is necessary to discriminate between the causes of semantic change, the results and the nature of the process of change of meaning.1 These are three closely bound up, but essentially different aspects of one and the same problem.
Discussing the causes of semantic change we concentrate on the factors bringing about -this change and attempt to find out w h y the word changed its meaning. Analysing the nature of semantic change we seek i See St. Ullmann. The Principles of Semantics. Chapter 8, Oxford, 1963. 28
to clarify the process of this change and describe how various changes of meaning were brought about. Our aim in investigating the results of semantic change is to find out w h a t was changed, i.e. we compare the resultant and the original meanings and describe the difference between them mainly in terms of the changes of the denotational components.
