On principle, feigned forbearance with which I answer Middle East expert (8,2,6)
I believe the answer is:
lawrence of arabia
'on' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'principle feigned forbearance with which i answer middle east expert' is the wordplay.
I cannot quite see how this works, but
'principle' could be 'law' (I've seen this in another clue) and 'law' is found in the answer.
an anagram of 'forbearance' is 'renceofarab' which is present in the answer.
'i' could be 'a' and 'a' is located in the answer.
A single letter 'i' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for lawrence of arabia that I've seen before include "Epic 1962 film" , "Author of The Seven Pillars of Wisdom" .)
