Enlightened writer's boss holds up English antique coin (8)
I believe the answer is:
educated
'enlightened writer's' is the definition.
'educated' can be an answer for 'enlightened' (thesaurus). I'm unsure of the 'writer's' bit.
'boss holds up english antique coin' is the wordplay.
'boss' becomes 'ed' (short for editor - newspaper boss).
'holds up' is a charade indicator (letters next to each other) (in a down clue, some letters go beneath others).
'english' becomes 'E' (abbreviation).
'antique coin' becomes 'ducat' (I've seen this before).
'e'+'ducat'='educat'
'ed' after 'educat' is 'EDUCATED'.
Can you help me to learn more?
(Other definitions for educated that I've seen before include "Trained; learned" , "Instructed, taught" , "Well-read" , "Enlightened, knowledgeable" , "Clever" .)
