Why is sentence "He is coming fast" wrong? Obviusly its different meaning, which its unrecognisable from one sentence.
I remember "geht" from "wei gehts?" and "mir geht's gut". Not sure how it translates into walk?
I think it works like this; So 'Wie geht's?' can be translated as 'How are you going?', so i think 'going' is applied in the same context/meaning as walking.
he goes quick is correct as well... quick is an adverb as well as an adjective
