Because of the ever closer connection between the oral and the written forms of the language it is sometimes difficult to differentiate clippings formed in oral speech from graphical abbreviations. The more so as the latter often pass into oral speech and become widely used in conversation.

It has already been mentioned that curtailed words from compounds are few; cases of curtailment combined with composition set off against phrasal prototypes are slightly more numerous, e. g. ad-lib v ‘to speak without notes or preparation’ from the Latin phrase ad libitum meaning ‘at pleasure’; subchaser n from submarine chaser. A curious derivational compound with a clipping for one of its stems is the word teen-ager (see p. 35). The jocular and ironical name Lib-Labs (Liberal Labour MP’s, i.e. a particular group) illustrates clipping, composition and ellipsis and imitation of reduplication all in one word.

An interesting pattern revealing the influence of extra-linguisticfactors on word-formation and vocabulary development are such compounds as camp-in, ride-in, teach-in, work-in and the like. "The Barn-hart Dictionary of New English” treats the second element as a combining form of the adverb in and connects the original appearance of this morpho-semantic pattern with the civil-rights movement of the 60s. It was used to nominate such public demonstrations of protest as riding in segregated buses (ride-in), praying in segregated churches (kneel-in), bathing in segregated swimming pools (swim-in).

Compounding, one of the oldest methods of word-formation occurring in all Indo-European languages, is especially developed in Germanic languages. English has made use of compounding in all periods of its existence. Headache, heartache, rainbow, raindrop and many other compounds of the type noun stem+noun stem and its variant, such as manslaughter

Rhyme combinations are twin forms consisting of two elements (most often two pseudo-morphemes) which are joined to rhyme: boogie-woogie, flibberty-gibberty ‘frivolous’, harum-scarum ‘disorganised’, helter-skelter ‘in disordered haste’, hoity-toity ‘snobbish’, humdrum ‘bore’, hurry-scurry ‘great hurry’, hurdy-gurdy ‘a small organ’, lovey-dovey ‘darling’, mumbo-jumbo ‘deliberate mystification, fetish’, namby-pamby ‘weakly sentimental’, titbit ‘a choice morsel’, willy-nilly ‘compulsorily’ (cf. Lat volens-nolens).

The reduplicative compounds resemble in sound form the rhyme combinations like razzle-dazzle and ablaut combinations like sing-song. These two types, therefore, are treated by many1 as repetition with change of initial consonant or with vowel interchange. H. Marchand treats these as pseudo-compounds, which occur as twin forms with phonic variation and as twin forms with a rhyme for characteristic feature.

In what follows we shall describe some combinations that may be called compounds by right of pattern, as they very markedly consist of two parts, but otherwise in most cases fail to satisfy our definition of a compound word. Some of them contain only one free form, the other constituents being a variation of this, while there are also cases where both constituents are jocular pseudo-morphemes, meaningless and fanciful sound clusters which never occur elsewhere. Their motivation is mostly based upon sound-symbolism and it is their phonetic make-up that plays the most important role in their functioning They are all stylistically coloured (either colloquial, slang or nursery words) and markedly expressive and emotional: the emotion is not expressed in the constituents but suggested by the whole pattern (reduplication rhyme).

Derivational compounds or compound-derivatives like long-legged do not fit the definition of compounds as words consisting of more than one free stem, because their second element (-legged) is not a free stem.

Scholars are not agreed on the question of compound verbs. This problem indeed can be argued in several different ways. It is not even clear whether verbal compositions exist in present-day English, though such verbs as outgrow, overflow, stand up, black-list, stage-manage and whitewash are often called compound verbs. There are even more complications to the problem than meet the eye.

Compound adjectives regularly correspond to free phrases. Thus, for example, the type threadbare consists of a noun stem and an adjective stem. The relation underlying this combination corresponds to the phrase ‘bare to the thread’. Examples are: airtight, bloodthirsty, carefree, heartfree, media-shy, noteworthy, pennywise, poundfoolish, seasick, etc.
