Expected round part of the house (5)
I believe the answer is:
owing
'expected' is the definition.
Both the answer and definition are adjectives. Perhaps you can see a link between them that I don't see?
'part of the house' is the wordplay.
I cannot quite see how this works, but
'part' could be 'wing' (wing is a kind of part) and 'wing' is found within the answer.
'of' could be 'o' and 'o' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'round' acts as a link.
Can you help me to learn more?
(Other definitions for owing that I've seen before include "This debt has yet to be paid" , "Still outstanding" , "Outstanding as a debt" , "(Of money) outstanding" , "Due to, like debt" .)
