Fruit swallowed by some Londoners (5)
I believe the answer is:
'fruit' is the definition.
(type of fruit)
'swallowed by some londoners' is the wordplay.
'MELON' is hidden in amongst the letters.
However, I'm uncertain how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for melon that I've seen before include "Large sweet gourd" , "Type of pepo" , "Sweet juicy fruit" , "Honeydew fruit" , "Large round fruit" .)
