Fruit needing flood regularly eaten by half of us? (5)
I believe the answer is:
melon
'fruit' is the definition.
(melon is a kind of fruit)
'flood regularly eaten by half of us?' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'eaten by' means one lot of letters goes inside another.
'half of us?' becomes 'men' (I can't justify this - if you can you should give a lot more credence to this answer).
The alternating letters of 'flood' are 'lo'.
'lo' placed within 'men' is 'MELON'.
'needing' is the link.
Can you help me to learn more?
(Other definitions for melon that I've seen before include "I'm very seedy" , "Killing" , "Cantaloupe fruit" , "Fruit - lemon (anag)" , "Type of pepo" .)
