Caught in possession? (3)
I believe the answer is:
had
'caught in possession?' is the definition.
The definition and answer can be both related to change as well as being past participle verbs.
Maybe they are linked in a way I don't understand?
This is all the clue.
Can you help me to learn more?
(Other definitions for had that I've seen before include "Did trick" , "Taken in" , "Was in possession of" , "Owned in the past" , "Was bound to be - caught" .)
