Catch many a snake (5)
I believe the answer is:
clasp
'catch' is the definition.
(I've seen this in another clue)
'many a snake' is the wordplay.
'many a' becomes 'cl' (I can't justify this - if you can you should believe this answer much more).
'snake' becomes 'asp' (asp is a kind of snake).
'cl'+'asp'='CLASP'
Can you help me to learn more?
(Other definitions for clasp that I've seen before include "Clutch" , "Part of a necklace" , "Grasp; fastener" , "Hold firmly or fasten" , "Bar on a medal ribbon" .)
