Talk about (7)
I believe the answer is:
discuss
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">talk about</span>' is the definition.<br/ ><span class="explanation-format__explanation">(to discuss something is to talk about it)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for discuss that I've seen before include "Go into" , "Debate" , "Consider" , "Verbally T [TREAT]" , "Talk about (something)" .)
