Amuse, touch lightly (6)
I believe the answer is:
tickle
I believe this clue is a double definition.
'amuse' is the first definition.
(I know that amuse can be written as tickle)
'touch lightly' is the second definition.

(Other definitions for tickle that I've seen before include "Catch (trout) by rubbing" , "Excite pleasurably" , "Amuse; make tingle" , "Stimulate" , "Titillate" .)
