Go over hill lapping Tesla? (6)
I believe the answer is:
revise
'go over' is the definition.
(go over can mean to revise or edit)
'hill lapping tesla?' is the wordplay.
'hill' becomes 'rise' (both can mean raised ground).
'lapping' indicates putting letters inside (lapping can mean covering or wrapping).
'tesla?' becomes 'ev' (I can't explain this - if you can you should believe this answer much more).
'rise' placed around 'ev' is 'REVISE'.
Can you help me to learn more?
(Other definitions for revise that I've seen before include "Swot for an exam" , "Go back over lesson" , "Improve, amend" , "Prepare for exams" , "Prepare for exam" .)
