For a big hit, yes, you get a kiss! (3)
I believe the answer is:
six
'for a big hit' is the definition.
(cricket)
'yes you get a kiss' is the wordplay.
'yes you' becomes 'si' (I can't explain this - if you can you should give a lot more credence to this answer).
'get' says to put letters next to each other.
'a kiss' becomes 'x' (X can represent a kiss).
'si'+'x'='SIX'
Can you help me to learn more?
(Other definitions for six that I've seen before include "Number of US moon landings" , "larger boundary" , "Airborne boundary hit" , "Maximum cricket hit" , "Knock for . . . - surprise or defeat" .)
