Caught and held (3)
I believe the answer is:
had
This clue might be a double definition.
'caught' is the first definition.
The definition and answer can be both related to change as well as being past participle verbs.
Maybe you can see a link between them that I can't see?
'held' is the second definition.
('have' can be a synonym of 'hold')
'and' acts as a link.
Can you help me to learn more?
(Other definitions for had that I've seen before include "Was in possession of" , "Taken in" , "Possessed; cheated" , "Did trick" , "Owned in the past" .)
