Mobile insured to include mother and nanny (9)
I believe the answer is:
nursemaid
'nanny' is the definition.
('nursemaid' can be a synonym of 'nanny')
'mobile insured to include mother' is the wordplay.
'mobile' indicates an anagram.
'to include' indicates putting letters inside.
'mother' becomes 'ma' (ma is a kind of mother).
'insured' anagrammed gives 'nurseid'.
'nurseid' enclosing 'ma' is 'NURSEMAID'.
'and' is the link.
(Other definitions for nursemaid that I've seen before include "She may attend to babe" , "her charges are small" , "child minder" , "female carer" , "employ one for small charge" .)
