Signature (9)
I believe the answer is:
autograph
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">signature</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know that autograph is a type of signature)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for autograph that I've seen before include "Signer will give this" , "Sign" , "(Celebrity's) signature" , "One's signed" , "One's signature" .)
