I believe the answer is:
able
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">up to the job</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for able that I've seen before include "Fit as a seaman" , "See 21" , "... was I ere I saw Elba (palindrome)" , "Competent and equipped" , "Efficient" .)
