Shouldn't you also be able to translate this as, "this woman is young"?
The word for young would be "जवान"
How would you distinguish this from "This is a short woman"? Would that be यह एक औरत छोटी है ?
यह एक छोटी औरत है
In hindi you can put the adjectives in front of the noun too. यह औरत छोटी है = this woman is short. यह एक छोटी औरत है = This is a short woman. Just follow the placement of the adjective in english.
Isn't there an actual word for short? Shouldn't this be "small"?
