Note: I am aware of the basic meaning and usage of far from and far away.
This post is NOT duplicate of Use of 'Far' and 'Far away.'. Since the answer to that post does not mention idiomatic and far from at all, besides that post is talking about physical distance rather than words-distance in sentence.
An ELL post gives a nice explanation.
"Far from..[x]" states a relative position from which you are measuring the distance.
So, I guess the following sentence uses far from in the right way.
Cambridge isn't far from London
On the other hand,
"Far away" presumes you are speaking relative to your present location.
A: "The city is far away"
That city is far from where the guy A lives.
Similar, I used far from in my another post (When the verb an adverb describes is far away, what should I do?)
I listened to the pronunciation of who on Cambridge Dictionary carefully.
(in the example sentence above, the adverb "carefully" is) a bit far from "listened".
Provided that post is to discuss the position of the adverb "carefully", similar to the guy A in previous example, is it grammatical and idiomatic to say in the following way?
the verb "listened" is far away.
