upstream
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">against the current</span>' is the definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for upstream that I've seen before include "Going back to the source" , "away from estuary?" , "Facing current" , "Away from the sea" , "Current trend is not" .)
