A member of the family in hospital? (6)
I believe the answer is:
sister
'a member of the family' is the definition.
'in hospital?' is the wordplay.
I cannot quite understand how this works, but
'in hospital?' could be 'er' (I've seen this in other clues) and 'er' is located in the answer.
The remaining letters 'sist' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for sister that I've seen before include "twin?" , "Relative in hospital?" , "Female relation" , "woman in hospital" , "A relative to resist" .)
