He looks after the nannies as well as the kids (8)
I believe the answer is:
goatherd
'he looks after the nannies as well as the kids' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'he looks after the' is the wordplay.
I cannot really understand how this works, but
'he' is within the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for goatherd that I've seen before include "Great hod (anag.)" , "one looking after kids" .)
