Alerted (8)
I believe the answer is:
notified
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">alerted</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for notified that I've seen before include "Informed, reported to" , "Told, informed" , "Officially informed" , "Formally informed" .)
