"A second type of direct evidence is formed by statements, whether as formal legends or personal info..." — Edward Sapir

These examples of the lack of simplicity in English and French, all appearances to the contrary, could be multiplied almost without limit and apply to all national languages.

So far as the advocates of a constructed international language are concerned, it is rather to be wondered at how much in common their proposals actually have, both in vocabulary and in general spirit of procedure.

No important national language, at least in the Occidental world, has complete regularity of grammatical structure, nor is there a single logical category which is adequately and consistently handled in terms of linguistic symbolism.

It is no secret that the fruits of language study are in no sort of relation to the labour spent on teaching and learning them.
