In addition, any word—this again applied in principle to every word in the language—could be negatived by adding the affix UN-, or could be strengthened by the affix PLUS-, or, for still greater emphasis, DOUBLEPLUS-. Thus, for example, UNCOLD meant ‘warm’, while PLUSCOLD and DOUBLEPLUSCOLD meant, respectively, ‘very cold’and ‘superlatively cold’. It was also possible, as in present- day English, to modify the meaning of almost any word by prepositional affixes such as ANTE-, POST-, UP-, DOWN-, etc. By such methods it was found possible to bring about an enormous diminution of vocabulary. Given, for instance, the word GOOD, there was no need for such a word as BAD, since the required meaning was equally well—indeed, better—expressed by UNGOOD. All that was necessary, in any case where two words formed a natural pair of opposites, was to decide which of them to suppress. DARK, for example, could be replaced by UNLIGHT, or LIGHT by UNDARK, according to preference.
