From part of empire, perhaps: no one local, sadly (8)

Ross

I believe the answer is:

colonial

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

'from part of empire' is the definition.
I can't judge whether this defines the answer.

'no one local sadly' is the wordplay.
'one' becomes 'i' (Roman numeral).
'sadly' indicates an anagram.
'no'+'i'+'local'='noilocal'
'noilocal' anagrammed gives 'COLONIAL'.

'perhaps' is the link.

Can you help me to learn more?

(Other definitions for colonial that I've seen before include "Of places ruled by distant governments" , "Like America before independence" , "Of a geographical area politically controlled by a distant country" , "Living in dependency" , "Relating to overseas dominions" .)
