Make serious effort (9)

Ross

I believe the answer is:

endeavour

(Other definitions for endeavour that I've seen before include "Try - Captain Cook's vessel" , "Cook's old vessel" , "Attempt by employing effort" , "Enterprise; earnest effort" , "Strive - over a nude (anag)" .)

I've seen this clue in The Sun.
