Correct Conjugation In Konjunktive II
My favorite conjugation website gives the K.II conjugation of Brauchen without the umlaut (http://conjugator.reverso.net/conjugation-german-verb-brauchen.html)
However, DL shows it with an umlaut (https://www.duolingo.com/skill/de/Verbs%3A-Conditional/tips-and-notes)
I tried looking it up but there seems to be some that do and some that don't give it with an umlaut. So is it ich bräuchte oder ich brauchte?
The formal version is brauchte. I rarely use brauchte though. I virtually always use the informal bräuchte in order to make clear that I'm not using simple past brauchte. Bräuchte is quite common. I'm not sure if that's typical for only certain regions, but it seems good enough to me. Alternatively, many Germans (count me in) say würde + infinitve (here: würde brauchen). That's not very formal, but a good way to circumnavigate the proper Konjunktiv II conjugation patterns.
Well, technically "ich brauchte" is right, but honestly no one uses this form in Germany, they use "ich bräuchte" which is more a "slang" form. But I am living in the south of Germany so can't exactly speak for the rest... :-/
Both brauchte and bräuchte are correct, but they have different meaning.
1) Ich brauchte ein neues Auto. = I needed a new car.
2) Ich bräuchte ein neues Auto. = I would need a new car.
