Egg on curry goes oddly unnoticed (4)
I believe the answer is:
urge
'egg on' is the definition.
(to egg on is to urge or encourage)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for urge that I've seen before include "Impel, egg on" , "Encourage to go on, goad" , "Strongly recommend; impulse" , "Egg on, encourage to proceed" , "Press to take action" .)
