Of similar character (4)
I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">of similar character</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for akin that I've seen before include "Related or similar - as a relative?" , "Similar in quality" , "Seemingly related" , "not totally similar" , "Related or similiar" .)
