Charm is a curious personal quality (8)
I believe the answer is:
charisma
'personal quality' is the definition.
'charisma' can be an answer for 'quality' (charisma is a kind of quality). I'm not certain of the 'personal' bit.
'charm is a curious' is the wordplay.
'curious' is an anagram indicator.
'charm'+'is'+'a'='charmisa'
'charmisa' with letters rearranged gives 'CHARISMA'.
Can you help me to learn more?
(Other definitions for charisma that I've seen before include "Compelling attractiveness" , "Alluring personal quality - archaism (anag)" , "magnetic quality" , "Drawing power" , "Impressive gift" .)
