Tube line used in returning from part of Epping? (4)
I believe the answer is:
pipe
'tube' is the definition.
(pipes are tubular)
'line used in returning from part of epping?' is the wordplay.
I cannot quite understand how this works, but
'from' could be 'e' (I've seen this in other clues) and 'e' is located in the answer.
The remaining letters 'pip' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for pipe that I've seen before include "Part of an organ; tube" , "Utter shrilly; wine cask" , "'Tube for water or gas, say (4)'" , "Tube to carry water, gas etc" , "Water carrier" .)
