City is feminine? Are there rules to learn which words are masculine and which words are feminine?
City is feminine?
Yes, it is.
Are there rules to learn which words are masculine and which words are feminine?
Unfortunately, there is no general rule about that. There are some partial rules (with some exception); for instance, words ending in -dad, like ciudad, are generally feminine.
Also, most of the time words that end in -a are feminine, and words that end with -e are masculine.
"The city is a very pretty?" That doesn't sound right in English or Spanish.
in an earlier lesson, I was marked incorrect when I put ciudad as feminine. Now they tell me I was right all along.
What's the difference between saying 'Es un ciudad..' and 'Esta ciudad es..'?
Es un ciudad... does not exist in Spanish, as ciudad is femenin. It should be Es una ciudad, and it means It is a citty, or it could be part of a longer sentence: Es una ciudad bonita = It's a pretty citty. Es = is.
Esta ciudad es... means This citty is.... Here, esta = this and es = is (as in the other sentence).
