Funny itch -- silk can make one sensitive (8)
I believe the answer is:
ticklish
'one sensitive' is the definition.
(I've seen this before)
'funny itch silk' is the wordplay.
'funny' is an anagram indicator.
'itch'+'silk'='itchsilk'
'itchsilk' anagrammed gives 'TICKLISH'.
'can make' is the link.
(Other definitions for ticklish that I've seen before include "Problematic" , "easy to get to laugh?" , "Easily made to laugh, or needing careful handling" , "Delicate - easily excited to laughter" , "Sensitive, needing delicate handling" .)
