Some Carib sentiment expressed by playwright (5)
I believe the answer is:
ibsen
'playwright' is the definition.
(I know that Ibsen is a playwright)
'some carib sentiment expressed' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'IBSEN' is hidden in the letters of 'carib sentiment expressed'.
'by' acts as a link.
(Other definitions for ibsen that I've seen before include "Author of The Master Builder, d. 1906" , "6 24 113 [SCAN-DIN-AVIAN] writer" , "Hedda Gabler author" , "Norwegian dramatist of 'Hedda Gabler'" , ""Doll's House" dramatist" .)
