Line dugout and wallow in it (7)
I believe the answer is:
indulge
'line' is the definition.
Although both the answer and definition are verbs in their base form, I don't see how they can define each other.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for indulge that I've seen before include "Pamper - eluding (anag)" , "Allow person to have what he/she wishes" , "Yield to the wishes of" , "Gratify, spoil" , "Enjoy to excess" .)
