"هٰذِهِ جامِعة جَميلة."

Translation: This is a pretty university.

[Absinthene]

Why pretty and not beautiful?

[phuvtuo]

Either should be fine.

I put in "This university is pretty", which wasn't accepted. Is there a different sentence structure that would translate to my sentence "This university is pretty"? Maybe with different cases?? Or in Arabic is it indistinguishable from "This is a pretty university".

[JW3yl7]

I have looked into it & I think a "this" or "that" makes something definite. Therefore it would be:

This university is pretty = "This The University is pretty" =
هٰذه الجامعةُ جميلة

This page helped (although it is talking more about iDaafa):

Correct. When the noun following هٰذا or هٰذه is definite (proceeded by ال, is a proper name, or an idaafa) it becomes 'This definite thing is adjective/adverb.'
