Crossword Genius

In addition to love (3)

Ross

I believe the answer is:

too

'in addition' is the definition.
(I've seen this in another clue)

'to love' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'to'+'o'='TOO'

(Other definitions for too that I've seen before include "Additionally" , "Moreover, in addition" , "Likewise" , "What a pity!" , "Excessively" .)

I've seen this clue in The Globe and Mail.
