Taste of weapon not yet used? (9)
I believe the answer is:
spearmint
'taste' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'weapon not yet used?' is the wordplay.
'weapon' becomes 'spear' (spear is a kind of weapon).
'not yet used?' becomes 'mint' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'spear'+'mint'='SPEARMINT'
'of' is the link.
Can you help me to learn more?
(Other definitions for spearmint that I've seen before include "Herb used for flavouring" , "Aromatic herb" , "Aromatic plant" , "fresh flavour" , "Strongly flavoured herb" .)
