Morphological and syntactic criteria can also be applied to compound words in order to distinguish them from word-groups.

In the word-group a tall boy each of the constituents is independently open to grammatical changes peculiar to its own category as a part of speech: They were the tallest boys in their form. Between the constituent parts of the word-group other words can be inserted: a tall handsome boy. The compound tallboy — and, in actual fact, any other compound — is not subject to such changes. The first component is grammatically invariable; the plural form ending is added to the whole unit: tallboys. No word can be inserted between the components, even with the compounds which have a traditional separate graphic form.
All this leads us to the conclusion that, in most cases, only several criteria (semantic, morphological, syntactic, phonetic, graphic) can convincingly classify a lexical unit as either a compound word or a word group.
Semi-Affixes
Consider the following examples.
"... The Great Glass Elevator is shockproof, waterproof, bombproof, bulletproof, and Knidproof1 ..." (From Charlie and the Great Glass Elevator by R. Dahl)
Lady Malvern tried to freeze him with a look, but you can't do that sort of thing to Jeeves. He is look-proof.
(From Carry on, Jeeves by P. G. Wodehouse)
Better sorts of lip-stick are frequently described in advertisements as kissproof. Some building materials may be advertised as fireproof. Certain technical devices are foolproof meaning that they are safe even in a fool's hands.
1Knids — fantastic monsters supposed to inhabit the Cosmos and invented by the author of this book for children.

All these words, with -proof for the second component, stand between compounds and derived words in their characteristics. On the one hand, the second component seems to bear all the features of a stem and preserves certain semantic associations with the free form proof. On the other hand, the meaning of -proof in all the numerous words built on this pattern has become so generalised that it is certainly approaching that of a suffix. The high productivity of the pattern is proved, once more, by the possibility of coining nonce-words after this pattern: look-proof and Knidproof, the second produced from the non-existent stem Knid. The component -proof, standing thus between a stem and an affix, is regarded by some scholars as a semi-affix.
Another example of semi-affix is -man in a vast group of English nouns denoting people: sportsman, gentleman, nobleman, salesman, seaman, fisherman, countryman, statesman, policeman, chairman, etc.
Semantically, the constituent -man in these words approaches the generalised meaning of such noun-forming suffixes as -er, -or, -ist (e. g. artist), -ite (e. g. hypocrite). It has moved so far in its meaning from the corresponding free form man, that such word-groups as woman policeman or Mrs. Chairman are quite usual. Nor does the statement Lady, you are no gentleman sound eccentric or illogical for the speaker uses the word gentleman in its general sense of a noble upright person, regardless of sex. It must be added though that this is only an occasional usage and that gentleman is normally applied to men.
Other examples of semi-affixes are -land (e. g. Ire land, Scotland, fatherland, wonderland), -like (e. g. ladylike, unladylike, businesslike, unbusiness like, starlike, flowerlike, etc.), -worthy (e. g. seaworthy, trustworthy, praiseworthy). 114
Shortening (Contraction)
This comparatively new way of word-building has achieved a high degree of productivity nowadays, especially in American English.
Shortenings (or contracted/curtailed words) are produced in two different ways. The first is to make a new word from a syllable (rarer, two) of the original word. The latter may lose its beginning (as in phone made from telephone, fence from defence), its ending (as in hols from holidays, vac from vacation, props from properties, ad from advertisement) or both the beginning and ending (as in flu from influenza, fridge from refrigerator). The second way of shortening is to make a new word from the initial letters of a word group: U.N.O. ['ju:neu] from the United Nations Organisation, B.B.C. from the British Broadcasting Corporation, M.P. from Member of Parliament. This type is called initial shortenings. They are found not only among formal words, such as the ones above, but also among colloquialisms and slang. So, g. f. is a shortened word made from the compound girl-friend. The word, though, seems to be somewhat ambiguous as the following conversation between two undergraduates clearly shows:
Who's the letter from?
My g. f.
Didn't know you had girl-friends. A nice girl?
Idiot! It's from my grandfather!
It is commonly believed that the preference for shortenings can be explained by their brevity and is due to the ever-increasing tempo of modern life. Yet, in the conversation given above the use of an ambiguous contraction does not in the least contribute to the brevity of the communication: on the contrary, it takes the speakers some time to clarify the misunderstand-

ing. Confusion and ambiguousness are quite natural consequences of the modern overabundance of shortened words, and initial shortenings are often especially enigmatic and misleading.
Both types of shortenings are characteristic of informal speech in general and of uncultivated speech particularly. The history of the American okay seems to be rather typical. Originally this initial shortening was spelt O.K. and was supposed to stand for all correct. The purely oral manner in which sounds were recorded for letters resulted in O.K. whereas it should have been AC. or aysee. Indeed, the ways of words are full of surprises.
Here are some more examples of informal shortenings. Movie (from moving-picture), gent (from gentleman), specs (from spectacles), circs (from circumstances, e. g. under the circs), I. O. Y. (a written acknowledgement of debt, made from I owe you), lib (from liberty, as in May I take the lib of saying something to you?), cert (from certainty, as in This enterprise is a cert if you have a bit of capital), metrop (from metropoly, e. g. Paris is a gay metrop), exhibish (from exhibition), posish (from position). Undergraduates' informal speech abounds in words of the type: exam, lab, prof, vac, hol, co-ed (a girl student at a coeducational school or college).
