Builder of a lodge (5)
I believe the answer is:
mason
'builder' is the definition.
(I know that mason is a type of builder)
'of a lodge' is the wordplay.
I cannot really see how this works, but
'of' could be 'o' and 'o' is found in the answer.
'a' is present in the answer.
The remaining letters 'msn' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for mason that I've seen before include "Craftsman - English film actor, d. 1984" , "one in construction" , "US comedian" , "One works with stone or brick" , "Builder in stone" .)
