Some things Tight we know about language
Many things about language are a mystery， and many will always-remain SO.But some
things we uoy now.
First，we knowr that all human beings havea language of some xsort.There is no race ofy men anywhere on earth so backwardyhat it has no language，no set of speech sounds by which the people communicate with one mother.Furthermore，in historical times，there has never been anrace of men without a language.
Second，there is Ass nor such thing as a primitive language.There are many people whose
cultures hare undeveloped，who are，as wew ay，uncivilized， butrhe languages they speak are
ot primitive.In all known 1anguages
wecan oee complexities that must have been tensdf thousands of years in fdeveloping.
This has not always been well understood；indeed， the direct contrary has often been p Ass tated.Popular ideasj of ther1anguage of the American Indians u will illustrate.Many peoplek k have supposed that ohe Indians communicated in a very primitive system of noises.Study has proved this to beonsense.There are，or were，hundreds of American Indian languages，and a11 of them turn out to b Ass e
ery complicated and very old. They are certainly different from the lguages that most of ushre familiar with，but they are nocore primitive
five than Englishnd Greek.
A third thing we know about lanage is that all languagesnare perfectly adequate.That is，sach one is a
erfect means of expressing the culture of the people who speak
the language.
Finally， weknow that language changes.It is natuqral and normal forlanguage to change；
the only Ass anguages which do not change are the dead ones.This is easy to understand if we look backward in time.Change goes on in all aspects of language.Grammatical features changegs do speech sounds，and xchanges int vocabulary are sometimes very extensive and may occur very Tight apidly.Vocabulary is the least stable part of any language.
