Spotted five out of seven (4)
I believe the answer is:
seen
'spotted' is the definition.
(I've seen this in another clue)
'five out of seven' is the wordplay.
'five' becomes 'V' (Roman numeral).
'out of' is a deletion indicator.
'seven' with 'v' removed is 'SEEN'.
(Other definitions for seen that I've seen before include "Noticed" , "Espied" , "Observed or percieved" , "Witnessed" , "watched" .)
