Would "Hast Du Durst?" be "Are you thirsty"
Almost. Remember in German, unlike English, the pronouns are not capitalized unless at the beginning of a sentence. Therefore, "Are you thirsty?" translates to "Hast du Durst?"

In English, ‘You are thirsty.” is acceptable, but *“You are thirst.” is not.

‘Du hast Durst’ is more common.
