Writer's mark fresh and natural in Old English (5,5)
I believe the answer is:
oscar wilde
'writer's' is the definition.
(I've seen this before)
'mark fresh and natural in old english' is the wordplay.
'mark fresh' becomes 'scar' (mark left by an injury. I am not sure about the 'fresh' bit.).
'and' is a charade indicator (letters next to each other).
'natural' becomes 'wild' (synonyms).
'in' indicates putting letters inside.
'old english' becomes 'OE'.
'scar'+'wild'='scarwild'
'scarwild' going within 'oe' is 'OSCAR WILDE'.
Can you help me to learn more?
(Other definitions for oscar wilde that I've seen before include "dramatist" , "He had nothing to declare but his genius" , "Irish-born writer and wit (1854-1900)" , "playwright" , "Irish writer and wit" .)
