Steal fruitfully (6)
I believe the answer is:
scrump
'steal' is the definition.
Both the answer and definition are verbs in their base form.
Maybe there's a link between them I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for scrump that I've seen before include "Steal (fruit) from an orchard" , "theft" , "Steal apples from trees" , "steal from farmer" , "Nick apples" .)
