What leads to court officials backing line that shouldn't be crossed (4)
I believe the answer is:
oche
'line that shouldn't be crossed' is the definition.
'oche' can be an answer for 'line' (I've seen this before). I'm not sure about the rest of the definition.
'what leads to court officials backing' is the wordplay.
'what' becomes 'eh' (sound used to ask 'what?' or 'pardon?').
'leads to' suggests taking the first letters.
'backing' says the letters should be written in reverse.
The first letters of 'court officials' is 'co'.
'eh'+'co'='ehco'
'ehco' written backwards gives 'OCHE'.
Can you help me to learn more?
(Other definitions for oche that I've seen before include "Behind which a darts player must stand" , "Line from which dart-players throw" , "Line where dart thrower stands" , "What darts player stands behind" , "Line from which dart-player throws" .)
