Labour suited to endless offices in The House (7)
I believe the answer is:
studies
'offices in the house' is the definition.
The answer and definition can be both acts as well as being plural nouns.
Perhaps there's an association between them I don't understand?
'labour suited to endless' is the wordplay.
I cannot quite see how this works, but
an anagram of 'suited' is 'studie' which is within the answer.
A single letter 's' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for studies that I've seen before include "Applies the mind to learning" , "Closely inspects; rooms" , "academic courses" , "Scrutinises" , "lessons" .)
