I believe the answer is:
addressee
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">recipient of a letter</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for addressee that I've seen before include "He's written to" , "Person named on an envelope" , "Intended recipient of letter" , "One sent letter" , "One contacted" .)
