Instant message notification sound able ultimately to have an effect (7)

Ross

I believe the answer is:

impinge

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

'have an effect' is the definition.
(I've seen this in another clue)

'instant message notification sound able ultimately' is the wordplay.
'instant message' becomes 'im' (this could be a standard abbreviation I've not previously seen).
'notification sound' becomes 'ping' (I've seen this in another clue).
'ultimately' says to take the final letters.
The final letter of 'able' is 'e'.
'im'+'ping'+'e'='IMPINGE'

'to' is the link.

Can you help me to learn more?
