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.
Perhaps they are linked in a way I don't understand?
'five out of seven' is the wordplay.
'five' becomes 'v' ('V' can be a synonym of 'five').
'out of' indicates named letters should be taken away.
'seven' with 'v' removed is 'SEEN'.
'getting' acts as a 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" .)
