Attractive quality causing hurt to many (5)
I believe the answer is:
charm
'attractive quality' is the definition.
'charm' can be an answer for 'quality' (charm is a kind of quality). I'm unsure of the 'attractive' bit.
'hurt to many' is the wordplay.
'hurt' becomes 'harm' (synonyms).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'many' becomes 'c' (C is the Roman numeral for h00).
'harm' put after 'c' is 'CHARM'.
'causing' acts as a link.
Can you help me to learn more?
(Other definitions for charm that I've seen before include "Bracelet ornament" , "Entrance, bewitch" , "Spell; ornament" , "Talisman; flock of goldfinches" , "Entrance; amulet" .)
