<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">tried out</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 tested that I've seen before include "Probed or analysed" , "Proven" , "Proved" , "Tried or examined" , "Subjected to examination, put through paces" .)
