Data about Eastern aspects (6)
I believe the answer is:
facets
'aspects' is the definition.
(I know this)
'data about eastern' is the wordplay.
I cannot quite see how this works, but
'about' could be 'c' (abbreviation for circa) and 'c' is found within the answer.
'eastern' could be 'e' and 'e' is located in the answer.
The remaining letters 'fats' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for facets that I've seen before include "Sides or surfaces" , "Surfaces of a cut gem" , "Faces of cut gemstones" , "Sides or aspects, diamonds or buildings" , "Surfaces or aspects" .)
