"Where do your daughters live?"
Translation:Ubi habitant filiae tuae?
I understand that Latin has very flexible word order; is that still so in the case of the question word "ubi", or must it be at the beginning? The reason I'm asking is because my answer of "Filiae tuae ubi habitant?" was marked incorrect, and I'm unsure whether it's a mistake on my part or Duolingo's (I did report it just in case). Sorry for the hassle!
Question forms take pesidence over all other word forms. Ubi and any 1st word (question forms) that end in ne. Est to estne. Sunt to suntne. And habitas to habitasne. You will never hear or see in california habitasne. Or sorores tuae ubi. And civitas estne. But will indeed stumble on ubi habitas or habitasne in italia.
It can be both, after or before, but always close to it.
Possessive adjectives, such as meus "my", suus "his/their", are fairly evenly distributed (68% preceding in Caesar, 56% in a sample of Cicero speeches). When a possessive follows the noun it is unemphatic.
So, I deduce from this, that the most common way to use possessive adjectives (my, your, etc...) is following the noun it modifies: "filiae tuae".
