Somewhat misleading description of Lewis, say (4)
I believe the answer is:
isle
'description of lewis say' is the definition.
'isle' can be an answer for 'description' (I have seen 'description of Britain' mean 'isle' so perhaps 'description' could also mean 'isle'). I'm not sure about the 'of lewis say' bit.
'somewhat misleading' is the wordplay.
'somewhat' indicates the answer is hidden within the clue.
'ISLE' can be found hidden inside 'misleading'.
Can you help me to learn more?
(Other definitions for isle that I've seen before include "being impossible without water" , "description of Britain" , "Land amid water" , "Small mass of land in the sea" , "Land cut off by water" .)
