Stone age container of a piece of meat (5)
I believe the answer is:
agate
'stone' is the definition.
(I know that agate is a type of calcedony\nI know that calcedony is a type of transparent gem\nTherefore, agate is a type of transparent gem\nI know that transparent gem is a type of gem\nTherefore, agate is a type of gem)
'age container of a piece of meat' is the wordplay.
I cannot quite see how this works, but
'a' is found in the answer.
'piece' could be 'gat' (both can mean a gun) and 'gat' is found within the answer.
A single letter 'e' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for agate that I've seen before include "Ornamental form of quartz" , "Hard stone with concentric bands of colour" , "Precious stone" , "Quartz variety" , "marble" .)
