Infant's nanny – I'd surname wrong (9)
I believe the answer is:
nursemaid
'infant's nanny' is the definition.
'nursemaid' can be an answer for 'nanny' (both can mean someone who looks after children). I'm not certain of the 'infant's' bit.
'i'd surname wrong' is the wordplay.
'wrong' indicates anagramming the letters.
'id'+'surname'='idsurname'
'idsurname' is an anagram of 'NURSEMAID'.
Can you help me to learn more?
(Other definitions for nursemaid that I've seen before include "Girl tending young children" , "Woman employed to look after children" , "Woman tending a child or children" , "Alice, for example" , "female carer" .)
