Egg on some hamburger (4)

I believe the answer is:

urge

'egg on' is the definition.
(to egg on is to urge or encourage)

'some hamburger' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'URGE' can be found hidden inside 'hamburger'.

(Other definitions for urge that I've seen before include "Implore" , "Press; drive" , "Propel, drive onward" , "Encourage; impulse" , "Sudden inclination to do something" .)

I've seen this clue in The Sun.
