506 The Loom of Language do so wŁ should be entitled to use the unclean for unckanlmess as well as for the unclean individuals The misery of all existing speech is that useful devices remain half-exploited Grammarians say that analogical extension has not gone far enough. English has now a simple and highly regularized fksaonal system,, but in its linguistic expression of concepts and relations it is as chaotic as any other language, including Esperanto. This is what foreigners mean when they say English is simple at the start, but, etc While we can design a language to achieve a high level of word- economy in Ogden's sense, and therefore to lighten the load which the beginner has to carry, there is no reason for restricting the vocabulary of an Interlanguage constructed with this end in view to the bare minimum of words essential for lucid communication, and we have no need to exclude the possibility of ringing the changes on synonyms which safeguard style against monotony. We might well add to our interdictionary an appendix containing a reserve vocabulary of compact alternatives. Even so, a maximum vocabulary of roots excluding all strictly technical terms and local names for local things or local institutions, need scarcely exceed a total of three thousand INTERPHONBTICS It would be easy to formulate the outstanding desiderata of an ideal language on the naive assumption that phonetic considerations are of prior importance, and it would not be difficult to give them practical expression. To begin with, we have to take stock of the fact that the consonant dusters (p. 214) so characteristic of the Aryan family are almost or completely absent in other languages, e.g in Chinese, Japan- ese, Bantu, and in Polynesian dialects So dusters of two or three consonants such as in blinds, and, more serious, quadruple combina- tions as in mustn't, are foreign to the ear and tongue of most peoples outside Europe, America, and India. Then again, few people have a range of either simple consonants or simple vowels as great as our own A five-fold battery of vowels with values roughly like those of the Italian and Spanish a, e, z, 0, u, suffices for many speech communities. Several of our own consonants are phonetic rarities, and many varieties of human speech reject the voiceless series in favour of the voiced, or vice versa A battery of consonants with very wide currency would not indude more than nine items—/, m, n, r, together with a choice between the series />, t,f, k, $, and the series b, d> v, g, z Even this would be a liberal allowance. The Japanese have no /,
