Bored by all the square-bashing? (7)
I believe the answer is:
drilled
'bored' is the definition.
(I've seen this before)
'by all the square-bashing?' is the wordplay.
'by' is a charade indicator (letters next to each other).
'all' becomes 'ed' (I can't explain this - if you can you should believe this answer much more).
'the square-bashing?' becomes 'drill' (square-bashing is a kind of drill).
'ed' after 'drill' is 'DRILLED'.
Can you help me to learn more?
(Other definitions for drilled that I've seen before include "Bored a hole or trained by repetition" , "Made a hole with a pointed tool" , "soldiers may be treated thus" , "given military instruction" .)
