How Hal and Al went into the butcher's business? (7)
I believe the answer is:
jointly
'how hal and al went' is the definition.
I can't tell whether this definition defines the answer.
'into the butcher's business?' is the wordplay.
I cannot really understand how this works, but
an anagram of 'into' is 'oint' which is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for jointly that I've seen before include "Collectively" , "Together" .)
