I am new to German and have searched for my question but couldn’t find any similar questions that explained why aus would appear at the end of a sentence.
Anyway, I’m learning German on Duolingo and a sentence that I have come across is
Er sieht klein aus.
He looks small.
and I don’t quite understand why there is a preposition at the end of the sentence. Is the aus necessary? Seems to me like the sentence is saying
He looks good out
which just sounds weird.
