English verbs of motion feel almost naked without a little adverb such as up, down, through, over or away, at least in conversational English. The prepositional phrase adds additional information. Because “away” and “from” have similar ideas, “away from” is a common collocation.
I think that “away from” is a common collocation not because “away” and “from” have similar ideas but because it is used frequently.
I'd like to know if the bold part is wrong.
