Love affair starts to affect my Open University revision (5)

I believe the answer is:

amour

'love affair' is the definition.
(I've seen this before)

'starts to affect my open university revision' is the wordplay.
'starts to' says to take the initial letters.
The first letters of 'affect my open university revision' is 'AMOUR'.

(Other definitions for amour that I've seen before include "beloved" , "Love-affair" , "French love affair, usually secret" , "Loved one (French)" , "(Secret) lover" .)

I've seen this clue in The Telegraph.
