One tenor coming from the east (6)
I believe the answer is:
orient
'east' is the definition.
(I know that east can be written as Orient)
'one tenor coming from' is the wordplay.
'one' becomes 'i' (Roman numeral).
'coming from' is an anagram indicator.
'i'+'tenor'='itenor'
'itenor' with letters rearranged gives 'ORIENT'.
'the' acts as a link.
(Other definitions for orient that I've seen before include "Leyton -- FC" , "Get one's bearings - to the East?" , "East; align" , "The mystic East?" , "Align relative to compass points" .)
