Be durable (4)
I believe the answer is:
last
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">be durable</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 last that I've seen before include "` `The cobler should stick to his ....' '" , "Cargo to stay fresh" , "Endure - this clue is!" , "Rearmost" , "Ultimate - endure" .)
