Relating to the meaning of words (8)
I believe the answer is:
semantic
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">relating to the meaning of words</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 semantic that I've seen before include "Relating to meaning in language" , "Relating to the meaning of words" , "about what words mean" , "Tin maces could relate to the meaning of words" , "Of difference in meaning of words" .)
