Demonstrate round residence topless come what may (7)
I believe the answer is:
somehow
'come what may' is the definition.
I can't tell whether this defines the answer.
'demonstrate round residence topless' is the wordplay.
'demonstrate' becomes 'show' (synonyms).
'round' indicates putting letters inside.
'residence' becomes 'home' (home is a kind of residence).
'topless' means to remove the first letter.
'home' with its first letter taken away is 'ome'.
'show' going around 'ome' is 'SOMEHOW'.
Can you help me to learn more?
(Other definitions for somehow that I've seen before include "One way or another" , "By hook or by crook" , "For an unknown reason; so who, me? (anag.)" , "By one means or another" , "By unspecified means" .)
