Remove salt from longboats in drums (5)
I believe the answer is:
bongo
'remove salt from longboats in drums' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'remove salt from longboats' is the wordplay.
'remove' indicates anagramming the letters (move the letters again).
'from' is a deletion indicator.
'longboats' with 'salt' removed is 'ongbo'.
'ongbo' anagrammed gives 'BONGO'.
Can you help me to learn more?
(Other definitions for bongo that I've seen before include "Small Cuban drum" , "Type of drum - central African antelope" , "Rare African antelope" , "Hand-played drum" , "One beaten" .)
