Is English permissible? Find out (6)
I believe the answer is:
elicit
'find out' is the definition.
(as in eliciting information)
'is english permissible?' is the wordplay.
'is english' becomes 'e' (abbreviation).
'permissible?' becomes 'licit' (I've seen this before).
'e'+'licit'='ELICIT'
(Other definitions for elicit that I've seen before include "Draw out, say a response" , "Bring out - evoke" , "Draw out from, invoke" , "Evoke (a response)" , "Draw out (response, information etc)" .)
