Old quarter-pound headgear? (5)
I believe the answer is:
crown
I believe this is a triple definition!
'old quarter' is the first definition.
'crown' can be an answer for 'quarter' (thesaurus). I am not sure about the 'old' bit.
'pound' is the second definition.
(thesaurus)
'headgear?' is the third definition.
(I know that crown is a type of headgear)
Can you help me to learn more?
(Other definitions for crown that I've seen before include "sporting award" , "Hit on the head (informal)" , "repair for damaged tooth" , "Visible part of a tooth" , "King" .)
