There's nothing in changing a rule, so take no notice (6)
I believe the answer is:
ignore
'take no notice' is the definition.
(I've seen this before)
'there's nothing in changing a rule' is the wordplay.
I cannot quite understand how this works, but
'there's' could be 'n' (I've seen this in other clues) and 'n' is found within the answer.
'nothing' could be 'o' (looks like zero - 0) and 'o' is present in the answer.
'rule' could be 'r' (legal abbreviation) and 'r' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'so' is the link.
Can you help me to learn more?
(Other definitions for ignore that I've seen before include "Neglect" , "set aside" , "Deliberately overlook" , "Cut head off" , "Region in which to snub" .)
