For one, the word can be taken as a reality check against a prominent idea concerning language.
Psychologists have since shown repeatedly that differences in how languages’ vocabularies label experience do condition very small differences in thought patterns.
In Russian, for instance, there is not one word for blue, but two: one for darker blue and one for lighter blue.
No experiment has demonstrated that differences in language affect our minds so profoundly as to result in significantly different world views.
It is culture — i.e., reality — that does that, not the specifics of how narrowly or broadly a word happens to apply.
