Older relative — of a kid? (5)
I believe the answer is:
nanny
'a kid?' is the definition.
(thesaurus)
'older relative' is the wordplay.
I cannot really see how this works, but
'relative' could be 'nan' (informal term for a grandmother) and 'nan' is present in the answer.
The remaining letters 'ny' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'of' is the link.
Can you help me to learn more?
(Other definitions for nanny that I've seen before include "Children's nurse" , "She cares for kids" , "Child minder - goat - grandma" , "Undue government interference with personal choice?" , "Child's nurse or female goat" .)
