They may put up houses for sale (8)
I believe the answer is:
builders
'they' is the definition.
Both the answer and definition are plural nouns.
Perhaps they are linked in a way I don't understand?
'put up houses for sale' is the wordplay.
I cannot quite understand how this works, but
'put up' could be 'build' (put up can mean to build or erect) and 'build' is found within the answer.
The remaining letters 'ers' 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).
'may' is the link.
Can you help me to learn more?
(Other definitions for builders that I've seen before include "Construction workers" , "Constructors" .)
