In darts, it's where to toe the line (4)
I believe the answer is:
oche
This could be a double definition.
'in darts it's where to toe' is the first definition.
I know that 'darts' relates to this answer.
'line' is the second definition.
(I've seen this before)
'the' is the link.
Can you help me to learn more?
(Other definitions for oche that I've seen before include "Line at which darts player stands to throw" , "Line of 25 [ARROEWS]" , "Line behind which an 11 player throws" , "Dart-playing line" , "Line behind which darts players stand" .)
