The catch on the charm bracelet? (10)
I believe the answer is:
silverfish
'the' is the definition.
I can't tell whether this defines the answer.
'catch on the charm bracelet?' is the wordplay.
'catch' becomes 'fish' (fishing is a kind of catching).
'on' is a charade indicator (letters next to each other).
'the charm bracelet?' becomes 'silver' (I can't justify this - if you can you should believe this answer much more).
'fish' put after 'silver' is 'SILVERFISH'.
Can you help me to learn more?
(Other definitions for silverfish that I've seen before include "Domestic insect, bristletail" , "Household insect" .)
