36 Semantis aspect of composition.

Semantically compound words are motivated units. The meaning of the compound is first of all derived from the combined lexical meanings of its components. The semantic peculiarity of the derivational bases and the semantic difference between the base and the stem is most obvious in compound words. The stem of the word board is polysemantic and its meanings serve as different derivational bases, each with its own selective range for the semantic features of the other component, each forming a separate set of compound words, based on ’specific derivative relations. Thus the base board meaning ‘a flat piece of wood square or oblong’ makes a set of compounds chess-board, notice-board, key-board, diving-board, foot-board, sign-board; the base board-meaning ‘an authorised body of men’, forms compounds school-board, board-room. The same can be observed in words built on the polysemantic stem of the word foot. For example, the base foot- in foot-print, foot-pump, foothold, foot-bath, foot-wear has the meaning of ‘the terminal part of the leg’, in foot-note, foot-lights, foot-stone the base foot- has the meaning of ‘the lower part’.

37 Polysemy of composition patterns.

The derivational patterns in compounds may be monosemantic, and polysemantic.² If we take the pattern п+а -> A snow-white, world-wide, air-sick, we shall see that the pattern has two different meanings which may be interpreted: a) through semantic relations of comparison between the components as in world-wide — ‘wide as the world’, snow-white — ‘as white as snow’, etc. and b) through various relations of adverbial type (circumstantial) as in road-weary — ‘weary of the road’, colour-blind — ‘blind to colours’, etc. The structural pattern n+n -> N that underlies compound nouns is also polysemantic and conveys different semantic relations such as relations of purpose, e.g. bookshelf, bed-room, relations of resemblance, e.g. needle-fish, bowler-hat, instrumental or agentive relations, e.g. steamboat, windmill, sunrise, dogbite.

The polysemy of the structure often leads to a certain freedom of interpretation of the semantic relations between the components and consequently to the polysemy of the compound.

38 Word-building meaning in composition

It follows that the meaning of a compound is made up of the combined lexical meaning of the bases and the structural meaning of the pattern. The semantic centre of the compound is the lexical meaning of the second component modified and restricted by the meaning of the first. The semantic centres of compounds and the semantic relations in the structural patterns refer compound words to certain lexico-semantic groups and semantic sets within them as, for example: 1) compound words denoting action described as to its agent, e.g. sunrise, earthquake, handshake, 2) compounds denoting action described as to its time or place, e.g. day-flight, street-fight, 3) compounds denoting individual objects designed for some goal, e.g. bird-cage, table-cloth, diving-suit, 4) compounds denoting objects that are parts of the whole, e.g. shirt-collar, eye-ball, 5) compounds denoting active doers, e.g. book-reader, shoe-maker, globe-trotter.

Mainly compound words are monosemantic and motivated but motivation in compounds like in all derivatives varies in degree. There are compounds that are completely motivated like sky-blue, foot-pump(педальный насос)
