§ 7.7 Back-formation

Back-formation (also called reversion) is a term borrowed from diachronic linguistics. It denotes the derivation of new words by subtracting a real or supposed affix from existing words through misinterpretation of their structure. The phenomenon was already introduced in § 6.4.3 when discussing compound verbs.

The process is based on analogy. The words beggar, butler, cobbler, or typewriter look very much like agent nouns with the suffix -er/-or, such as actor or painter. Their last syllable is therefore taken for a suffix and subtracted from the word leaving what is understood as a verbal stem. In this way the verb butle ‘to act or serve as a butler’ is derived by subtraction of -er from a supposedly verbal stem in the noun butler. Butler (ME buteler, boteler from OFr bouteillier ‘bottle bearer’) has widened its meaning. Originally it meant ‘the man-servant having charge of the wine’. It means at present ‘the chief servant of a rich household who is in charge of other servants, receives guests and directs the serving of meals’.

These examples are sufficient to show how structural changes taking place in back-formation became possible because of semantic changes that preceded them. In the above cases these changes were favoured by contextual environment. The change of meaning resulted in demotivation, and this paved the way for phonic changes, i.e. assimilation, loss of sound and the like, which in their turn led to morphemic alternations that became meaningful. Semantic changes often influence the morphological structure by

modifying the relations between stems and derivational affixes. Structural changes, in their turn, depend on the combined effect of demotivation and analogy conditioned by a higher frequency of occurrence of the pattern that serves as model. Provided all other conditions are equal, words following less frequent structural patterns are readily subjected to changes on the analogy of more frequent patterns.

The very high frequency of the pattern verb stem+-er (or its equivalents) is a matter of common knowledge. Nothing more natural therefore than the prominent part this pattern plays in back-formation. Alongside the examples already cited above are burgle v<burglar n; cobble v<cobbler n; sculpt v<sculptor n. This phenomenon is conveniently explained on the basis of proportional lexical oppositions. If

teacher ₌ painter ₌ butler teach paint x

then x = butle, and to butle must mean ‘to act as butler’.

The process of back-formation has only diachronic relevance. For synchronic approach butler : : butle is equivalent to painter : : paint, so that the present-day speaker may not feel any difference between these relationships. The fact that butle is derived from butler through misinterpretation is synchronically of no importance. Some modern examples of back-formation are lase v — a verb used about the functioning of the apparatus called laser (see p. 143), escalate from escalator on the analogy of elevate — elevator. Cf. also the verbs aggress, automate, enthuse, obsolesce and reminisce.

Back-formation may be also based on the analogy of inflectional forms as testified by the singular nouns pea and cherry. Pea (the plural of which is peas and also pease) is from ME pese<OE pise, peose<Lat pisa, pl. of pesum. The ending -s being the most frequent mark of the plural in English, English speakers thought that sweet peas(e) was a plural and turned the combination peas(e) soup into pea soup. Cherry is from OFr cerise, and the -se was dropped for exactly the same reason.

The most productive type of back-formation in present-day English is derivation of verbs (see p. 126) from compounds that have either -er or -ing as their last element. The type will be clear from the following examples: thought-read v<thought-reader n<thought-reading n; air-condition v<air-conditioner n < air-conditioning n; turbo-supercharge v < turbo-supercharger n. Other examples of back-formations from compounds are the verbs baby-sit, beachcomb, house-break, house-clean, house-keep, red-bait, tape-record and many others.

The semantic relationship between the prototype and the derivative is regular. Baby-sit, for example, means to act or become employed as a baby-sitter’, that is to take care of children for short periods of time while the parents are away from home. Similarly, beachcomb is ‘to live or act as a beachcomber’; the noun is a slightly ironical word de-

The degree of substantivation may be different. Alongside with complete substantivation of the type already mentioned (the private, the private’s, the privates), there exists partial substantivation. In this last case a substantivised adjective or participle denotes a group or a class of people: the blind, the dead, the English, the poor, the rich, the accused, the condemned, the living, the unemployed, the wounded, the lower-paid.

We call these words partially substantivised, because they undergo no morphological changes, i.e. do not acquire a new paradigm and are only used with the definite article and a collective meaning. Besides they keep some properties of adjectives. They can, for instance, be modified by adverbs. E.g.: Success is the necessary misfortune of human life, but it is only to the very unfortunate that it comes early (Trollope). It was the suspicious and realistic, I thought, who were most easy to reassure. It was the same in love: the extravagantly jealous sometimes needed only a single word to be transported into absolute trust (Snow).

Besides the substantivised adjectives denoting human beings there is a considerable group of abstract nouns, as is well illustrated by such grammatical terms as: the Singular, the Plural, the Present, the Past, the Future, and also: the evil, the good, the impossible. For instance: “One should never struggle against the inevitable,” he said (Christie)/

It is thus evident that substantivation has been the object of much controversy. Some of those, who do not accept substantivation of adjectives as a variant of conversion, consider conversion as a process limited to the formation of verbs from nouns and nouns from verbs. But this point of view is far from being universally accepted.
