Enlistee (7)
I believe the answer is:
recruit
'enlistee' is the definition.
(I know that enlistee can be written as recruit)
This is the entire clue.
(Other definitions for recruit that I've seen before include "Recently enlisted soldier" , "New member of army etc" , "New entrant as to the army or police" , "He's just joined up, often the armed forces" , "Newly enlisted member of a force" .)
