Say hello to (5)
I believe the answer is:
greet
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">say hello to</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 greet that I've seen before include "Acknowledge" , "Make welcome" , "Welcome; cry (Scots)" , "Address on arrival, say hello" , "Receive - salute" .)
