Is seeing television commercial in reverse? (5)
I believe the answer is:
dates
'is seeing' is the definition.
(to date someone is to see them romantically)
'television commercial in reverse?' is the wordplay.
'television' becomes 'set' (television set).
'commercial' becomes 'ad' (abbreviation for advertisement).
'in reverse?' is a reversal indicator (I've seen 'in reverse' mean this).
'set'+'ad'='setad'
'setad' reversed gives 'DATES'.
(Other definitions for dates that I've seen before include "Small tree-fruits or social appointments" , "Particular times" , "Goes steady" , "Specified parts of the year" , "Sated (anag) - fruit" .)
