Endless path round Orient oddly going westward (7)
I believe the answer is:
eternal
'endless' is the definition.
(I've seen this before)
'round orient oddly going westward' is the wordplay.
'round' indicates putting letters inside.
'oddly' indicates alternate letters (letters in the odd-numbered positions are used).
'going' becomes 'lane' (I can't explain this - if you can you should give a lot more credence to this answer).
'westward' says the letters should be written in reverse.
The alternate letters of 'orient' are 'ret'.
'ret' inserted into 'lane' is 'lanrete'.
'lanrete' back-to-front is 'ETERNAL'.
'path' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for eternal that I've seen before include "Timeless" , "with lasting benefit" , "Seemingly without end" , "Such a city is Rome" , "unchanged by time" .)
