mil

I'm a little stuck... Click here to teach me more about this clue!

'not far' is the definition.
I can't judge whether this defines the answer.

'from familiar' is the wordplay.
'from' indicates a hidden word.
'MIL' is hidden within 'familiar'.

Can you help me to learn more?

(Other definitions for mil that I've seen before include "tiny distance" , "One thousandth of an inch" , "One / one thousand inch" , "One thousanth of an inch" .)

I've seen this clue in the Evening Standard.
