Made sure of getting five out of seven (4)
I believe the answer is:
seen
'made sure of' is the definition.
The definition and answer can be both related to thinking as well as being past participle verbs.
Maybe there's a link between them I don't understand?
'five out of seven' is the wordplay.
'five' becomes 'V' (Roman numeral).
'out of' indicates named letters should be taken away ('out of' can mean no longer having).
'seven' with 'v' removed is 'SEEN'.
'getting' is the link.
Can you help me to learn more?
(Other definitions for seen that I've seen before include "Met - understood" , "Spotted" , "Perceived by sight" , "Noticed" , "Observed or percieved" .)
