In Palladium a cat sprang (7)
I believe the answer is:
pounced
'sprang' is the definition.
The answer and definition can be both to do with motion as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?
'in palladium a cat' is the wordplay.
'in' means one lot of letters goes inside another.
'palladium' becomes 'Pd' (Pd is the chemical symbol for palladium).
'a cat' becomes 'ounce' (ounce can mean a snow leopard).
'pd' placed around 'ounce' is 'POUNCED'.
Can you help me to learn more?
(Other definitions for pounced that I've seen before include "Swooped in attack" , "Sprang (like a cat)" , "Was jumping" , "Moved fast" , "Suddenly sprang" .)
