The Hunter (5)
I believe the answer is:
orion
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">the hunter</span>' is the definition.<br/ ><span class="explanation-format__explanation">(constellation)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for orion that I've seen before include "Greek hunter of myth or bright constellation" , "Mythical Greek hunter turned into constellation" , "Greek hunter became a constellation" , "Bright constellation, named after legendary Greek hunter" , "Prominent constellation" .)
