The letters in the German alphabet look just like the ones in the English alphabet, but there are four extra letters:
ä, ö, ü, ß
ä sounds like the a in the word game.
The word gähnen means yawn, and it sounds like gain-en. - /?/
ö sounds like the u in the word put.
The word Löwe means lion, and it sounds like luavah - /?/
ü sounds like the oo in the word soon.
The word müde means tired, and it sounds like moo-dah - /?/
ß sounds like the letter s, just held out a little longer.
The word Straße means street, and it sounds like strah-ss-ss-uh. - /?/
