Nothing of the sort is actually the case.
Take the inhabitants of that cheerless spot, Tierra del Fuego, whose culture is as rude as that of any people on earth.

A scholar who tried to put together a dictionary of their language found that he had got to reckon with more than thirty thousand words, even after suppressing a large number of forms of lesser importance.

And no wonder that the tally mounted up.

For the Fuegians had more than twenty words, some containing four syllables, to express what for us would be either "he" or "she"; then they had two names for the sun, two for the moon, and two more for the full moon, each of the last-named containing four syllables and having no element in common.

Sounds, in fact, are with them as copious as ideas are rare.
