Understand, when tucking into meat, about greens (7)
I believe the answer is:
vegetal
'understand when tucking into meat about greens' is the definition.
I can't judge whether this defines the answer.
'understand when tucking into meat' is the wordplay.
'understand' becomes 'get' (getting is a kind of understanding).
'when tucking into' is an insertion indicator.
'meat' becomes 'veal' (veal is a kind of meat).
'get' inserted into 'veal' is 'VEGETAL'.
Can you help me to learn more?
(Other definitions for vegetal that I've seen before include "Herbs are" , "Like cauliflower" .)
