Go ahead of (7)
I believe the answer is:
precede
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">go ahead of</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for precede that I've seen before include "Come or go before" , "Go ahead of" , "be in the van" , "Go before in time or order" , "Go in front" .)
