Crosses and gently touches (6)
I believe the answer is:
kisses
'touches' is the definition.
(kiss is a kind of touch)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for kisses that I've seen before include "Lightly touches" , "Osculates" , "caresses" , "Smackers" , "Light touches" .)
