Some children worried about person with pet? (5)
I believe the answer is:
owner
'person with pet?' is the definition.
I can't tell whether this definition defines the answer.
'some children worried about' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'about' is a reversal indicator.
'renwo' is hidden in the letters of 'children worried'.
'renwo' reversed gives 'OWNER'.
Can you help me to learn more?
(Other definitions for owner that I've seen before include "Man of property" , "Person having property" , "Holder, possessor" , "Person with legal title to something" , "Possessor, proprietor" .)
