Design pitched roof separating home from home with round centrepiece (9)
I believe the answer is:
intention
'design' is the definition.
(I know that design can be written as intention)
'pitched roof separating home from home with round centrepiece' is the wordplay.
I cannot quite see how this works, but
'home' could be 'in' ('he's home' can mean 'he's in') and 'in' is present in the answer.
'from' could be 'o' (I've seen this in other clues) and 'o' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for intention that I've seen before include "Aim, purpose" , "goal" , "Design" , "Aim, objective" , "end" .)
