At the start (9)
I believe the answer is:
initially
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">at the start</span>' is the definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for initially that I've seen before include "In the beginning" , "At the start" , "Firstly" , "To begin with" , "At first" .)
