Cut out returning strain after duke's been admitted to hospital? (10)
I believe the answer is:
'cut out' is the definition.
(I've seen this before)
'returning strain after duke's been admitted to hospital?' is the wordplay.
I cannot really see how this works, but
'admitted' could be 'in' (eg someone might be admitted into a group) and 'in' is present in the answer.
'hospital?' could be 'h' (abbreviation for hospital on maps) and 'h' is found within the answer.
'duke' could be 'd' (abbreviation) and 'd' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for disinherit that I've seen before include "Remove as heir" , "Cut off as with a shilling" , "Write out of a will" , "Lanarkshire town" .)
