Nurse person entitled regularly to have assistance round in the morning (4,2,3,4)
I believe the answer is:
lady of the lamp
'nurse' is the definition.
(nickname of Florence Nightingale)
'person entitled regularly to have assistance round in the morning' is the wordplay.
I cannot really see how this works, but
'person' could be 'lady' (lady is a kind of person) and 'lady' is found in the answer.
'round' could be 'o' (round can mean a round object) and 'o' is found within the answer.
'morning' could be 'am' and 'am' is located in the answer.
'assistance' could be 'help' (synonyms) and 'help' is found in the leftover letters.
This may be the basis of clue (or it may be nonsense).
(Another definition for lady of the lamp that I've seen is " Florence Nightingale".)
