The chap with the child I accommodated in a splendid home (7)
I believe the answer is:
mansion
'home' is the definition.
(I know that mansion is a type of house)
'the chap with the child i accommodated in' is the wordplay.
'the chap with' becomes 'man' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'the child' becomes 'son' (male child).
'accommodated in' is an insertion indicator.
'son' placed around 'i' is 'sion'.
'man'+'sion'='MANSION'
'a splendid' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for mansion that I've seen before include "Manor house" , "housing" , "Stately home" , "Grand house" , "Imposing house" .)
