Distant from strange person (6)

I believe the answer is:

offish

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

'distant' is the definition.
(synonyms)

'from strange person' is the wordplay.
'from' becomes 'off' (I've seen this in other clues).
'strange person' becomes 'ish' (I am not sure about this - if you are sure you should believe this answer much more).
'off'+'ish'='OFFISH'

Can you help me to learn more?

(Another definition for offish that I've seen is " Aloof, distant in manner".)

I've seen this clue in The Sunday Times.
