Can mirth cut thrill? (6)
I believe the answer is:
tingle
'thrill?' is the definition.
(synonyms)
'can mirth cut' is the wordplay.
'can' becomes 'tin' (synonyms).
'mirth' becomes 'glee' (I've seen this before).
'cut' means to remove the last letter.
'glee' with its last letter taken off is 'gle'.
'tin'+'gle'='TINGLE'
(Other definitions for tingle that I've seen before include "Sensational thrill" , "Smart" , "Stinging or thrilling sensation" , "Slight prickling sensation" , "Prickling or slightly stinging sensation" .)
