Raised weapon acquires valuable titbits (7)
I believe the answer is:
nuggets
'valuable titbits' is the definition.
Although both the answer and definition are plural nouns, I can't see how they can define each other.
'raised weapon acquires' is the wordplay.
'raised' shows that the letters should be reversed in order (going up in a down clue).
'weapon' becomes 'gun' (gun is a kind of weapon).
'acquires' becomes 'gets' ('get' can be a synonym of 'acquire').
'gun' backwards is 'nug'.
'nug'+'gets'='NUGGETS'
Can you help me to learn more?
(Other definitions for nuggets that I've seen before include "Lumps of metal like gold" , "Small lumps of gold" , "Solid lumps of a precious metal" .)
