§ 11. Derivational Patterns

Neither bases nor affixes alone can predict all the structural and semantic properties of words the ICs of which they may be. It is the combination of bases and affixes that makes up derivatives of different structural and semantic classes. Both bases and affixes due to the distributional meaning they possess show a high degree of consistency in their selection and are collocated according to a set of rules known as derivational patterns. Aderivational pattern is a regular meaningful arrangement, a structure that imposes rigid rules on the order and the nature of the derivational bases and affixes that may be brought together. A pattern is a generalisation, a scheme indicative of the type of ICs, their order and arrangement which signals the part of speech, the structural and semantic peculiarities common to all the individual words for which the pattern holds true. Hence the derivational patterns (DP) may be viewed as classifiers of non-simple words into structural types and within them into semantic sets and subsets. DPs are studied with the help of distributional analysis at different levels. Patterns of derivative structures are usually represented in a generalised way in terms of conventional symbols: small letters v, n, a, d, пит stand for the bases which coincide with the stems of the respective parts of speech: verbs, nouns, adjectives, adverbs, numerals; v_ed, v_ing stand for the bases which are the past and present participles respectively. In words of the long-fingered or sit-inner type the derivational bases are represented by bracketed symbols of the parts of speech making up the corresponding collocations, for example (a+n)+ +-ed), (v+d) + er.
DPs may represent derivative structure at different levels of generalisation:

1. 
   at the level of structural types specifying only the class membership of ICs and the direction of motivation, such as a+-sf -> N, prf- + +n -> V, prf- n -> N, n + -sf -> N, n + -sf -> V, etc. In terms of patterns of this type, known as structural formulas,¹ all words may be classified into four classes: suffixal derivatives, e.g. friendship, glorified, blackness, skyward; prefixal derivatives, e.g. rewrite, exboxer, non-smoker, un-happy, etc.; conversions, e.g. a cut, to parrot, to winter, etc.; compound words key-ring, music-lover, wind-driven, etc. But derivational formulas are not indicative either of any one lexical-grammatical or lexical class of words, as, for example, the formula a + -sf may equally represent suffixal nouns as in blackness, possibility and verbs, as in sharpen, widen, or adjectives as in blackish.

classes and individual affixes thus indicating the lexical-grammatical and lexical classes of derivatives within certain structural classes of words. DPs of this level are based on the mutual interdependence of individual affixes and base classes and may be viewed in terms of each. The suffixes refer derivatives to specific parts of speech and lexical subsets as, for example, v + -er -> N signals that the derivatives built on this pattern are de-verbal nouns which represent a semantic set of active agents, denoting both animate and inanimate objects, e.g. reader, runner, singer, unlike, for example, denominal nouns with the underlying pattern п+ -еr -> N which stands for agents denoting residents or occupations, e.g. Londoner, villager, gardener. The DP n+-ish -> A signals a set of adjectives with the lexical meaning of resemblance, whereas a + -ish -> A signals adjectives meaning a small degree of quality, etc.
c) DPs may be specified as to the lexical-semantic features of both ICs. DPs of this level specify the semantic constraints imposed upon the set of derivatives for which the pattern is true and hence the semantic range of the pattern. For example, the nominal bases in the pattern n+-ess -> N are confined to nouns having in their semantic structures a component ‘a male animate being’, e.g. lioness, traitress, stewardess, etc.; the nominal bases in n+-ful₂ -> N are limited by nouns having a semantic component ‘container’, e.g. lungful, carful, mouthful, whereas in n+ -ful₁ -> A the nominal bases are confined to nouns of abstract meaning. The same is true of the pattern n + -y -> A which represents different semantic sets of derivatives specified by semantic constraints imposed on both the bases and the suffix: nominal bases denoting living beings are collocated with the suffix -y meaning ‘resemblance’, e.g. birdy, spidery, catty, etc., but nominal bases denoting material, parts of the body attract another meaning of the suffix -y that of ‘considerable amount, size’ resulting in the adjectives like powdery, grassy, leggy, starry, etc.
It follows that derivational patterns may be classified into two types — structural pattern (see b, above) and structural-semantic pattern (see c).
