ABSTRACT
THE BASIS OF CLASSIFICATION 61 any cl&sl. The nearest approach to the former state is found, not in any of our natural languages, but in an artificial language such a.a Esperanto or, still better, Ido, where every common substantive ends in -0 (in the plural in -i), every adjective in -a, every (derived) adverb in -e, every verb in -r, -8, or -% according to its mood. The opposite state in which there are no formal signs to show wordclasses is found in Chinese, in which some words can only be used in cert&in applications, while others without any outward change may function now as substantives, now as verbs, now as adverbs, etc., the value in each case being shown by syntactic rules and the context.
