For instance (3)
I believe the answer is:
say
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">for instance</span>' is the definition.<br/ ><span class="explanation-format__explanation">(both can be used to introduce an example)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for say that I've seen before include "Utter; e.g." , "Judge" , "Chance to speak" , "Speak, declare" , "Speak, utter" .)
