§ 29. Classification

Compound words may be described from different points of view and consequently may be classified according to different principles. They may be viewed from the point of view: 1) of general relationship and degree of semantic independence of components; 2) of the parts of speech compound words represent; 3) of the means of composition used to link the two ICs together; 4) of the type of ICs that are brought together to form a compound; 5) of the correlative relations with the system of free word-groups.

Each type of compound words based on the above-mentioned principles should also be described from the point of view of the degree of its potential power, i.e. its productivity, its relevancy to the system of Modern English compounds. This description must aim at finding and setting a system of ordered structural and semantic rules for productive types of compound words on analogy with which an infinite number of new compounds constantly appear in the language.
