Palladium's youth centre (3)
I believe the answer is:
lad
This clue might be a double definition.
'palladium's youth' is the first definition.
'lad' can be an answer for 'youth' (lad means a young man). I'm not certain of the 'palladium's' bit.
'centre' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
Can you help me to learn more?
(Other definitions for lad that I've seen before include "Chap, fellow" , "Stable worker" , "Son" , "Boy or youth" , "Shaver" .)
