Vegetable brings a girl out in spots (6)
I believe the answer is:
radish
'vegetable' is the definition.
(radish is a type of vegetable)
'a girl out in spots' is the wordplay.
'a girl out' becomes 'di' (I am not sure about this - if you are sure you should believe this answer much more).
'in' means one lot of letters goes inside another.
'spots' becomes 'rash' (as in skin irritation).
'di' placed within 'rash' is 'RADISH'.
'brings' is the link.
Can you help me to learn more?
(Other definitions for radish that I've seen before include "Small red salad vegetable" , "Daikon or mooli" , "3 down" , "Root vegetable used in salads" , "Root eaten raw in salads" .)
