Second prize for pirate (6)
I believe the answer is:
silver
This might be a double definition.
'second prize' is the first definition.
'silver' can be an answer for 'second' (I've seen this before). I'm not sure about the 'prize' bit.
'pirate' is the second definition.
(I've seen this before)
'for' acts as a link.
Can you help me to learn more?
(Other definitions for silver that I've seen before include "Precious stuff" , "treasure" , "Silver of precious metal" , "Long John - -" , "symbolically a twenty-fifth" .)
