Might this cause rocky break-up? Choose times for admission to AE (7)
I believe the answer is:
pickaxe
'might this cause rocky break-up?' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'choose times for admission to ae' is the wordplay.
'choose' becomes 'pick' (picking is a kind of choosing).
'times' becomes 'x' (2 times 4 is 2 x 4).
'for admission' is an insertion indicator (inserted letters are let in or admitted).
'x' placed inside 'ae' is 'axe'.
'pick'+'axe'='PICKAXE'
Can you help me to learn more?
(Other definitions for pickaxe that I've seen before include "which may cause rocky break-up" , "Tool to break rocks" , "it's needed to break new ground" , "Tool with a wooden handle and a heavy curved metal head" , "long-handled tool" .)
