Disregard anger about navy entering game (6)
I believe the answer is:
ignore
'disregard' is the definition.
(I know that disregard can be written as ignore)
'anger about navy entering game' is the wordplay.
I cannot really see how this works, but
'about' could be 're' ('re' means regarding or about) and 're' is located in the answer.
'navy' could be 'n' (common abbreviation eg in RN Royal Navy) and 'n' is found in the answer.
'game' could be 'go' (go is a board game) and 'go' is found within the remaining letters.
A single letter 'i' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for ignore that I've seen before include "Deliberately take no notice" , "'Disregard, overlook (6)'" , "Pass over" , "Neglect" , "Forget" .)
