Procedure on defining both possibilities for batter? (7)
I believe the answer is:
routine
'procedure' is the definition.
(routine is a kind of procedure)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for routine that I've seen before include "Customary" , "habit" , "Fixed programme" , "every day" , "Schedule, standard procedure" .)
