§ 5. Transformational Analysis

Transformational analysis in lexicological investigations may be defined as re-patterning of various distributional structures in order to discover difference or sameness of meaning of practically identical distributional patterns.
As distributional patterns are in a number of cases polysemantic, transformational procedures are of help not only in the analysis of semantic sameness / difference of the lexical units under investigation

but also in the analysis of the factors that account for their polysemy.
For example, if we compare two compound words dogfight and dogcart, we shall see that the distributional pattern of stems is identical and may be represented as n+n. The meaning of these words broadly speaking is also similar as the first of the stems modifies, describes, the second and we understand these compounds as ‘a kind of fight’ and ‘a kind of cart’ respectively. The semantic relationship between the stems, however, is different and hence the lexical meaning of the words is also different. This can be shown by means of a transformational procedure which shows that a dogfight is semantically equivalent to ‘a fight between dogs’, whereas a dogcart is not ‘a cart between dogs’ but ‘a cart drawn by dogs’.
Word-groups of identical distributional structure when re-patterned also show that the semantic relationship between words and consequently the meaning of word-groups may be different. For example, in the word-groups consisting of a possessive pronoun followed by a noun, e.g. his car, his failure, his arrest, his goodness, etc., the relationship between his and the following nouns is in each instant different which can be demonstrated by means of transformational procedures.
his car (pen, table, etc.) may be re-patterned into he has a car (a pen, a table, etc.) or in a more generalised form may be represented as A possesses B.
