2. Аffixation

Аffixation is the formation of words by adding derivational affixes to different types of derivational bases. Affixal derivatives in the English language are coined by derivational prefixes and suffixes, that is why affixation is subdivided into prefixation and suffixation. Prefixes are the derivational morphemes preceding the root of the word, suffixes follow the root. Both prefixes and suffixes change the lexical meaning of the word and in many cases they change the part-of-speech meaning, e.g. case – encase, truth – truthful, etc.

There are distinguished different degrees of derivation depending on the number of applications of a word-formation rule. Simple words have a zero degree of derivation: atom, haste, devote. Derived words formed by application of one derivational affix have the first degree of derivation: atomic, hasty, devotion. Derived words formed by two consecutive stages of word-formation possess the second degree of derivation: atomical, hastily, devotional [Ginzburg 1979: 114].

In many cases subdivision of a word into a prefixal or suffixal derivative presents no difficulty. It is evident that untrue, discount, decode are prefixal derivatives; friendly, booklet, childhood are suffixal derivatives. But in case of three-morpheme words as unreasonable, discouragement and the like one should determine the arrangement and the nature of the ICs constituting these words, i.e. its derivative structure. Morphemically the words unreasonable, discouragement are identical, they are prefixal-radical-suffixal (consisting of a prefix, a root and a suffix), but according to their derivative structure the word unreasonable is a prefixal derivative: its ICs are un- and -reasonable (‘not reasonable’), and discouragement is a suffixal derivative, its ICs being discourage- and -ment (‘sth. that discourages’).

Suffixes may be affixed straight to the root morpheme (read - reader), or make up chains of suffixes occurring in the derived words having two and more suffixal morphemes: faith – faith|ful – faith|ful|ness). Suffixes of these kind are often referred to as compound suffixes. However, compound suffixes do not always present a mere succession of two or more suffixes arising out of consecutive stages of derivation. Some of them acquire a new quality operating as a whole unit [Ginzburg 1979: 119]. If we compare, on the one hand, such words as fascination (fascinate- + -ion), translation (translate- + -ion) with information (inform- + -ation), adaptation (adapt- + -ation), we see that they have different derivative structures. The words fascination and translation are the first-degree derivatives built with the suffix -ion, the words information and adaptation are the first-degree derivatives formed from the bases inform- and adapt- as there are no such bases as *informate-, *adaptate-. Thus the suffix -ation is a specific suffix of composite nature consisting of two suffixes -ate and -ion, but in many cases it functions as a single unit in first-degree derivatives. It is referred to in linguistic literature as a coalescent or a group suffix.

Suffixes might be added both to derivational bases made up of free roots (post- + -age) and bound roots (dam- + -age).

A prefix may be confined to one part of speech as in decode, encircle, etc. or may function in more than one part of speech: overcautious adj., overdo v., overpayment n. Suffixes as a rule function in any one part of speech: beautiful adj., darken v., connection n. The part-of-speech meaning is more prominent in suffixes. It was revealed that suffixation is mostly characteristic of noun (kindness, friendship, childhood, etc.) and adjective formation (beautiful, capable etc.) while prefixation is mostly typical of verb formation (to overcome, to disregard, to mispronounce, etc.) [Ginzburg 1979: 115]. Of course there are many cases of suffixal verbs: to darken, to realize, prefixal nouns income, underwear, etc. and adjectives uneasy, disloyal, etc. Suffixes to a greater extent than prefixes are used for converting words from one part of speech to another: care n. > careful a., good a. > goodness n., suit v. > suitable a., swim v. - swimmer n., etc. More often than not the part-of-speech meaning is determined by the suffix e.g. -ness, -ship, -ess, -hood etc. are noun suffixes; -able, -al, -less, etc. are adjective suffixes; -en, -ize –verb suffixes.

It is also noteworthy that suffixes are more closely knit with the bases than prefixes which are semantically less dependent on the base. As it was pointed above, some of the prefixes coincide in form and partially in meaning with the form words like out-, over-, up-, under-.
