Several wanting Germany instead of Southern Hemisphere (4)
I believe the answer is:
dome
'hemisphere' is the definition.
(hemispherical architectural feature)
'several wanting germany instead of southern' is the wordplay.
I cannot quite understand how this works, but
'germany' could be 'd' (vehicle registration code for Deutschland) and 'd' is present in the answer.
'of' could be 'o' and 'o' is located in the answer.
The remaining letters 'me' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for dome that I've seen before include "Rounded vault of a roof" , "Mode or arched roof" , "Rounded roof; Greenwich tent" , "millennium feature" , "description of church roof?" .)
