Bit of a radical vegetable? (6)
I believe the answer is:
radish
'bit' is the definition.
(I have seen 'Bit of salad' mean 'radish' so perhaps 'bit' could also mean 'radish')
'of a radical vegetable?' is the wordplay.
'of' indicates anagramming the letters (the answer comes from or 'of' the letters).
'radical' becomes 'r' (chemistry abbreviation).
'vegetable?' becomes 'dish' (I can't justify this - if you can you should believe this answer much more).
'a'+'r'='ar'
'ar' anagrammed gives 'ra'.
'ra'+'dish'='RADISH'
Can you help me to learn more?
(Other definitions for radish that I've seen before include "Sir had this vegetable" , "Pungent fleshy edible root eaten in salads" , "Red cold salad ingredient" , "3 down" , "Daikon or mooli" .)
