Greek somewhat ticklish? Somewhat (5)
I believe the answer is:
attic
'greek' is the definition.
(Attic is an example)
'somewhat ticklish? somewhat' is the wordplay.
'somewhat' indicates a hidden word.
'ATTIC' is hidden in the letters of 'somewhat ticklish'.
(Other definitions for attic that I've seen before include "High level of" , "Top level" , "Small room at the top" , "Greek - upper room" , "Loft room" .)
