Designer makes Catholic dose with ecstasy during play (9)
I believe the answer is:
architect
'designer' is the definition.
(I know that Architect is a type of designer)
'catholic dose with ecstasy during play' is the wordplay.
'catholic' becomes 'RC' (Roman Catholic).
'dose with' becomes 'hit' (hit is a kind of dose. I am not sure about the 'with' bit.).
'ecstasy' becomes 'E' (informal term for the drug).
'during' indicates putting letters inside.
'play' becomes 'act' (synonyms).
'rc'+'hit'+'e'='rchite'
'rchite' put within 'act' is 'ARCHITECT'.
'makes' is the link.
Can you help me to learn more?
(Other definitions for architect that I've seen before include "Author" , "Wren perhaps" , "Designer of buildings" , "Perhaps Scott" , "Building designer" .)
