Derivational Affixes

Derivational affixes are ICs of numerous derivatives in all parts of speech. Derivational affixes differ from affixational morphemes in their function within the word, in their distribution and in their meaning. Derivational affixes possess two basic functions:

1. that of stem-building which is common to all affixational morphemes: derivational and non-derivational. It is the function of shaping a morphemic sequence, or a word-form or a phrase into the part of the word capable of taking a set of grammatical inflections and is conditioned by the part-of-speech meaning these morphemes possess.

2. that of word-building which is the function of repatterning a derivational base and building a lexical unit of a structural and semantic type different from the one represented by the source unit. The repatterning results in either transferring it into the stem of another part of speech or transferring it into another subset within the same part of speech.

Ex. the derivational suffix -ness applied to bases of different classes shapes derived stems thus making new words. In kindliness, girlishness, etc. it repatterns the adjectival stems kindly-, girlish-, in second-rate-ness, allatonceness it turns the phrases second rate, all at once into stems and consequently forms newnouns.

In most cases derivational affixes perform both functions simultaneously shaping derived stems and marking the relationship between different classes of lexical items. However, certain derivational affixes may in individual sets of words perform only one function that of stem-building.

Ex. The derivational suffix -ic for example performs both functions in words like historic, economic, classic as it is applied to bases history-, economy-, class- and forms stems of words of a different part of speech. But the same suffix -ic in public, comic, music performs only its stem-building function shaping in this case a simple stem.

Besides, the non-derivational affixes shape only simple stems, for example, the morpheme -id in stupid, rapid, acid, humid; the morpheme -ish in publish, distinguish, languish. It follows that non-derivational morphemes are not applied to stems, but only to root-morphemes or morpheme sequences.

Semantically derivational affixes are characterised by a unity of part-of-speech meaning, lexical meaning and other types of morphemic meanings unlike non-derivational morphemes which, as a rule, lack the lexical type of meaning.

Ex. Prefixes like en-, un-, de-, out-, be-, unmistakably possess the part-of-speech meaning and function as verb classifiers when they make an independent IC of the derivative, e.g. deice, unhook, enslave.

1) The lexical (denotational) meaning of a generic type proper mostly not to an individual affix but to a set of affixes, forming a semantic subset such as, for example, the meaning of resemblance found in suffixes -ish, -like, -y, -ly (spiderish, spiderlike, spidery); the causative meaning proper to the prefix en- (enslave, enrich), the suffixes –ise (-ize), -(i)fy (brutalise, formalise, beautify, simplify, etc.); the meaning of absence conveyed by the prefix un- and the suffix -less; the meaning of abstract quality conveyed by the suffixes -ness, -ity, etc.

2) On the other hand derivational affixes possess another type of lexical meaning — an individual meaning shared by no other affix and thus distinguishing this particular affix from all other members, of the same semantic group. For example, suffixes -ish, -like, -y all have the meaning of resemblance, but -like conveys an overall resemblance, -ish conveys likeness to the inner, most typical qualities of the object, -y in most cases conveys likeness to outer shape, form, size of the object. Derivational affixes semantically may be both mono- and polysemantic.

Semi-affixes:

There is a specific group of morphemes whose derivational function does not allow one to refer them unhesitatingly either to the derivational affixes or bases. In words like half-done, half-broken, half-eaten and ill-fed, ill-housed, ill-dressed the ICs half- and ill- are given in linguistic literature different interpretations: they are described both as bases and as derivational prefixes. The ICs ill- and half- are losing both their semantic and structural identity with the stems of the independent words. These morphemes that are changing their class membership regularly functioning as derivational prefixes but still retaining certain features of root-morphemes. That is why they are sometimes referred to as semi-affixes. To this group we should also refer well- and self- (well-fed, well-done, self-made), -man in words like postman, cabman, chairman, -looking in words like foreign-looking, alive-looking, strange-looking
