486 The Loom of Language type can be feed authoritatively in such a way that the general structure will remain stable, though new words will, of course, be constantly added when need requires This family likeness will become increasingly apparent in what follows. We shall now examine principles of design with due regard to the measure of agreement to which Jespersen draws attention and to later issues which have emerged, more especially from discussion of the merits and defects of simple English. One of the conspicuous defects of Anglo-American m its present form is the difficulty men- tioned at the end of the last paragraph but one Its script, particularly the spelling of its inherited stock of monosyllables, has become well- nigh ideographic, and this is the most striking difference between any form of authentic English and any modern constructed language All advocates of a constructed international auxiliary agree that it must have consistent, simple, straightforward spelling rules, based on the use of the Roman alphabet. Since existing languages such as Italian, Spanish., and Norwegian furnish models of orderly behaviour, there has never been any practical difficulty about prescribing a system of phonetic spelling. A representative international committee of experts entrusted with the task of laying the foundations of a constructed world-auxiliary would waste few days in reaching agreement about its spelling conventions. Spelling raises only one outstanding issue for discussion Consistent spelling may mean either or both of two proposals' (a) that every sound has one symbol and one only, (6) that every symbol stands for a single sound. To insist too rigorously on the first has a disadvantage touched on in Chapter II Different languages have different conven- tions of alphabetic script, and the imposition of a rule limiting one sound to one symbol alone would therefore mutilate otherwise familiar roots beyond easy recognition. For example, we should not recognize the root chrom- in panchromatic or polychrome as easily if we spelt it with an initial ft, and the retention of two symbols for some sounds, e g CH or K for ft, would not appreciably add to the difficulties of learning. ESSENTIAL GRAMMAR It is also safe to say that grammar no longer provides much fuel for controversy among interhnguists. We have moved far since the days of Volapitk) and the main outlines of an international grammar are now dear enough The reader of The Loom of Language no longer needs to
