"Are you thirsty?"
Translation:Hast du Durst?
Only in more or less the situations where you could ask "You're thirsty??!" with a rising inflection -- i.e. when you heard something surprising and you want to make sure that you heard correctly.
It's not the neutral way to form a yes-no question, in either language.
Is that most of the adjective about feeling can be applied in this 'having' way?
No. The ones I can think of a Hunger, Durst, Angst haben (be hungry, thirsty, afraid).
Some temperature adjectives are "it is ... to me/him/her", e.g. mir ist kalt/warm (I am cold/warm).
Most other feelings use "to be" as in English: ich bin müde/frustriert/verwirrt "I am tired/frustrated/confused".
Can you explain why we are allowed to say 'ich habe durst' is right
Please pay attention to the spelling -- Durst is a noun and so it has to be capitalised.
ich habe Durst = I am thirsty.
while 'du hast durst' is wrong.
du hast Durst would be perfectly fine for "you are thirsty".
But here, you're asked to translate "are you thirsty?" -- a question, not a statement.
So you need Hast du Durst?.
If it did not accept Hast du Durst?, then you might have had a listening exercise rather than a translation exercise -- or you might have had some other small typo.
If you're sure it was neither of those, I can't guess what might have happened -- a link to an uploaded screenshot would be helpful.
Because the subject du requires the verb form hast.
habt would be the verb form for ihr.
So if you are asking one person, you would say, Hast du Durst?
And if you are asking several people at once, you would say Habt ihr Durst?
The verb form has to match the pronoun that you use.
Just like you can't say "Am you thirsty?" or "Is you thirsty?" -- the pronoun "you" requires the verb form "are" in English.
Yes, it is. All nouns are capitalised in German.
This is mentioned in the tips and notes for the very first unit.
