Always heard after goal or try (9)
I believe the answer is:
endeavour
'try' is the definition.
(I know that try can be written as endeavour)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for endeavour that I've seen before include "The first handle inspector has" , "Try hard (to achieve)" , "Morse" , "Determined effort" , "Aspire; attempt" .)
