Restrict an arsenic symbol in fruit (7)
I believe the answer is:
bananas
'fruit' is the definition.
(I've seen this before)
'restrict an arsenic symbol in' is the wordplay.
'restrict' means to remove the last letter (I've seen 'restricted' mean this (restricted can mean limited or reduced)).
'arsenic' becomes 'As' (As is the chemical symbol for arsenic).
'symbol' becomes 'bans' (I can't explain this - if you can you should believe this answer much more).
'in' is an insertion indicator.
'an'+'as'='anas'
'anas' with its final letter removed is 'ana'.
'ana' going into 'bans' is 'BANANAS'.
Can you help me to learn more?
(Other definitions for bananas that I've seen before include "nutty" , "Fruit; mad" , "Fruit - nuts" , "off 27 [TROLLEY]" , "hands" .)
