Hit ten again? (5)
I believe the answer is:
score
'hit' is the definition.
(synonyms)
'ten again?' is the wordplay.
'ten' becomes 'sco' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'again?' becomes 're' (prefix meaning 'again').
'sco'+'re'='SCORE'
Can you help me to learn more?
(Other definitions for score that I've seen before include "Number of runs" , "Tally; 20" , "Deeply scratch" , "Result" , "Twenty; scratch" .)
