Make an escape after fellow vegetable (9)
I believe the answer is:
mangetout
'fellow vegetable' is the definition.
'mangetout' can be an answer for 'vegetable' (I've seen this before). I'm not certain of the 'fellow' bit.
'make an escape after' is the wordplay.
'make' becomes 'm' (this might be a standard abbreviation I've not previously seen).
'escape' becomes 'get-out' (I've seen this in another clue).
'after' means one lot of letters go next to another.
'm'+'an'+'getout'='MANGETOUT'
Can you help me to learn more?
(Other definitions for mangetout that I've seen before include "Type of pea" , "Sugar peas" , "vegetables" , "Vegetable" , "something on the plate" .)
