Regard for number one? (4-6)
I believe the answer is:
self-esteem
'regard for number one?' is the definition.
I can't judge whether this defines the answer.
'regard for number one?' is the wordplay.
'regard' becomes 'esteem' (esteeming is a kind of regarding).
'for' is a charade indicator (letters next to each other) (I've seen this in other clues).
'number one?' becomes 'self' (I've seen this in another clue).
'esteem' put after 'self' is 'SELF-ESTEEM'.
Can you help me to learn more?
(Another definition for self-esteem that I've seen is " Confidence in one's own abilities and worth".)
