<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">taught a skill</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 trained that I've seen before include "ran along track" , "Taught (to do a job)" , "Schooled" , "I daren't (anag)" , "Coached" .)
