Stop, for example, in Hebridean island (8)

Ross

I believe the answer is:

colonsay

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

'hebridean island' is the definition.
(I've seen this before)

'stop for example' is the wordplay.
'stop' becomes 'colon' (I can't explain this - if you can you should believe this answer much more).
'for example' becomes 'say' ('say' can be used to introduce an example).
'colon'+'say'='COLONSAY'

'in' acts as a link.

Can you help me to learn more?

(Other definitions for colonsay that I've seen before include "Hebridean island" , "Scottish island" .)

I've seen this clue in The Times.
