Carrier (6)
I believe the answer is:
bearer
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">carrier</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that carrier can be written as bearer)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for bearer that I've seen before include "native servant" , "Coffin carrier (one paid on demand?)" , "One who helps to carry something - maybe news" , "Messenger - coffin-carrier" , "Carrier to whom cheque may be payable" .)
