Bandage put on tot, one firing missiles across the pond (9)
I believe the answer is:
slingshot
'one firing missiles across the pond' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'bandage put on tot' is the wordplay.
'bandage' becomes 'sling' (sling is a type of bandage).
'put on tot' becomes 'shot' (I can't justify this - if you can you should believe this answer much more).
'sling'+'shot'='SLINGSHOT'
Can you help me to learn more?
(Other definitions for slingshot that I've seen before include "that can help you get a stone off" , "No slights (anag) - catapult (US)" , "Sing Holst? (Anag)" , "Weapon American kid may produce" , "fatal to Goliath" .)
