I believe the answer is:
fair
<span class="explanation-format__ClueExplanation">This clue is a double definition.<br/ ><br/ >'<span class="explanation-format__original">reasonable</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(I know that reasonable can be written as fair)</span><br/ ><br/ >'<span class="explanation-format__original">just</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(just can mean fair in the sense of showing justice)</span><br/ ><br/ ></span>
(Other definitions for fair that I've seen before include "promotional exhibition" , "Equitable ? - trade show" , "Equitable - market - not bad" , "Equitable, just (4)" , "Pretty good" .)
