§ - 3. Classification of prefixes.

Unlike suffixation, which is usually bound up with the paradigm of a certain part of speech, prefixation is con­sidered to be neutral in this respect. It is significant that in linguistic literature derivational suffixes are always divided into noun-forming, adjective-forming, etc. Prefixes, however, are treated differently. They are described either in alphabetical order or subdivided into several classes in ac­cordance with their origin, meaning or function and never according to the part of speech formed. Some linguists even hold the view that one and the same prefix may be added to different parts of speech, cf. un-kind and un-tie. All this testifies to the fact that the problem of prefixation wants further investigation. It is hardly possible, for instance, to regard un- in unkind and un- in untie as the same pre­fix, for these two morphemes differ in meaning: in the first case un- has a negative meaning, and in the second it indicates reversal of an action. Therefore it would be more correct to consider them as being two homonyrnous prefixes: un-added to adjectival stems and an- affixed to verbal stems.

Prefixes may be classified on different principles. Diachronically distinction is made between prefixes of native and foreign origin. Synchronically, prefixes are classified according to the meaning they convey to the derived word. This is of great practical value in classroom teaching. The following groups of prefixes may be distinguished:

1) prefixes of negative meaning such as: un-, in-, dis- and some others, e.g. ungrateful (cf. grateful); unemployment (cf. employment); incorrect (cf. correct); disadvantage (cf. advantage), etc.

It may be mentioned in passing that the prefix in- oc­curs in different phonemic shapes depending on the initial sound of the stem it is affixed to; in other words, the prefixal morpheme in question has several allomorphs, namely il- (before [l]), im- (before [p, m]), ir- (before [r]), in- in all other cases, e.g. illegal, improbable, immaterial, irreligious, inactive, etc.
2) prefixes denoting reversal or repetition of an action such as un-, dis-, re- and some others, e.g. to unfasten (cf. to fasten), to disconnect (cf. to connect), to re-write (cf. to write), etc.
3) prefixes denoting space and time relations such as fore-, pre-, post-, over-, super- and some others, e.g. to foresee (cf. to see), pre-historic (cf. historic), post-position (cf. position), to overspread (cf. to spread), superstructure (cf. structure), etc.

As is the case with suffixes there are prefixes which are characterized by neutral stylistic reference and those possess­ing quite a definite stylistic value. To give but one exam­ple: the prefix over- occurs in all styles of speech, whereas the prefix super- is peculiar to the style of scientific prose. Like suffixes, prefixes may also be classified as productive or non-productive. Two examples will suffice here: the prefix re- is highly productive in Modern English, the prefix ill- is not.

The majority of prefixes affect only the lexical meaning of words but there are some important cases where prefixes serve to form words belon­ging to different parts of speech as compared with the original word.

These are in the first place the verb-forming prefixes be- and en-, which combine functional meaning with a certain variety of lexical meanings. Be- forms transitive verbs with adjective and noun stems and changes intransitive verbs into transitive ones. Examples are: belittle v ‘to make little'; benumb v 'to make numb'; befriend v 'to treat like a friend'; becloud v (bedew) v, befoam v) 'to cover with clouds (with dew or with foam)'; bemadam v 'to call madam'; besiege v 'to lay siege on'. Sometimes the lexical meanings are very different; compare, for instance, bejewel v 'to deck with jewels' and behead v which has the meaning of 'to cut the toad from'. There are on the whole about six semantic verb-forming va­rieties and one that makes adjectives from noun stems following the pattern be- + noun stem + -ed, as in benighted, bespectacled, etc. The pat­tern is often connected with a contemptuous emotional colouring.
The prefix en-/em- is now used to form verbs from noun stems with the meaning 'put (the object) into, or on, something', as in embed, engulf, encamp, and also to form verbs with adjective and noun stems with the meaning 'to bring into such condition or state', as in enable v, enslave v, encash v. Sometimes the prefix en-/em- has an intensifying function, cf. enclasp.
The prefix a- is the characteristic feature of the words belonging to statives: aboard, afraid, asleep, awake, etc.
This prefix has several homonymous morphemes which modify only the lexical meaning of the stem. Cf. arise v, amoral adj.
The prefixes pre-, post-, non-, anti- and some other Romanic and Greek prefixes very productive in present-day English serve to form adjec­tives retaining at the same time a very clear-cut lexical meaning, e.g. anti-war, pre-war, post-war, non-party, etc.
The borderline cases present considerable difficulties for classification. It is indeed not easy to draw the line between derivatives and compound words or between derivatives and root words. Such morphemes expressing relationships in space and time as after-, in-, off-, on-, out-, over-, under-, with- and the like which may occur as free forms have a combining power at least equal and sometimes even superior to that of the affixes. Their function and meaning as well as their position are exactly similar to those characteristic of prefixes. They modify the respective stems for time, place or manner exactly as prefixes do. They also are simi­lar to prefixes in their statistical properties of frequency. And yet prefixes are bound forms by definition, whereas these forms are free. This accounts for the different treatment they receive in different dictionaries. Thus Hornby's Dictionary considers aftergrowth a derivation with the prefix after-, while similar formations like afternoon, afterglow or afterthought are classified as compound nouns. Webster's Dictionary does not consider after- as a prefix at all. The Concise Oxford Dictionary alongside with the preposition and the adverb on gives a prefix on- with the examples: on­coming, onflow, onlooker, whereas in Chambers's Dictionary oncome v is treated as a compound.
The other difficulty concerns borrowed morphemes that were never active as prefixes in English but are recognized as such on the analogy with other words also borrowed from the same source. A strong protest against this interpretation was expressed by N. N. Amosova. In her opinion there is a very considerable confusion in English linguistic liter­ature concerning the problem of the part played by foreign affixes in English word-building. This author lays particular stress on the distin­ction between morphemes that can be separated from the rest of the stem and those that cannot. Among the latter she mentions the following prefixes listed by H. Sweet: amphi-, ana-, apo-, cato-, exo-, en-, hypo-, meta-, sina- (Greek) and ab-, ad-, amb- (Latin). The list is rather a mixed one. Thus, amphi- is productive in terminology and is with good reason considered by dictionaries a combining form (amphitheatre, amphibiotic 'terrestrial in adult state but aquatic as a larva'). Ana- in such words as anachronism, anagram, anaphora is easily distinguished, because the words readily lend themselves for analysis into immediate constituents. The prefix ad- derived from Latin differs very much from these two, being in fact quite a cluster of allomorphs assimilated with the first sound of the stem: ad-/ac-/af-/ag-/al-/ap-/as-/at-. E.g. adverbial, accumulation, affirm, aggravation, etc.
On the synchronic level the differentiation suggested by N. N. Amosova is irrelevant and the principle of analysis into immediate constitu­ents depends only on the existence of other similar cases.
