"The quantity is small."

Translation: La kvanto estas malgranda.

Why is 'eta' wrong?

[srtokes]

I believe that "eta" doesn't really mean small, but more to a small extent. For instance "Cxi tiu homo estas ete granda" (or cxi tiu homo estas grandeta) would mean "This man is a little tall". It doesn't mean that this man is both tall and small, but just that he is tall to a small extent. You can do the same with other adjectives: "La ovo estas varmeta / ete varma" is "The egg is hot to a small exent", or "The egg is warm". I hope this clears it up for you. :)

Nope. Eta means "small". Ete could mean "to a small extent", though, I believe.

[srtokes]

Ah, okay. Thanks for pointing it out. :D

cxu oni diras: "la kvanto malgrandas"?

Etymology of kvanto

From English quantity, French quantité, etc., ultimately from Latin quantitas.

[Vegemighty]

I would have though Esperanto would use different words for small when referring to either size or quantity.
