Received over a thousand (4)
I believe the answer is:
took
'received' is the definition.
The answer and definition can be both related to change as well as being past participle verbs.
Perhaps there's a link between them I don't understand?
'over a thousand' is the wordplay.
'over' becomes 'too' (I've seen this before).
'a thousand' becomes 'k' (synonyms).
'too'+'k'='TOOK'
Can you help me to learn more?
(Other definitions for took that I've seen before include "Helped oneself to" , "Small stem of flowers" , "Received - stole" , "Purloined" , "Seized" .)
