Abundant vegetation in meadow, fully empty (5)
I believe the answer is:
leafy
'abundant vegetation in' is the definition.
Both the definition and answer are adjectives. Perhaps you can see a link between them that I can't see?
'meadow fully empty' is the wordplay.
'meadow' becomes 'lea' (I've seen this before).
'empty' means to remove the middle letters.
'fully' with its centre taken out is 'fy'.
'lea'+'fy'='LEAFY'
Can you help me to learn more?
(Other definitions for leafy that I've seen before include "Abounding with trees" , "Like the better class suburbs?" , "Full of foliage" , "more shady places?" , "Like nice suburbs" .)
