<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">estimates</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I know this)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for guesses that I've seen before include "Opinions formed with little or no information" , "Hypothesises" , "Forms tentative opinion, thinks likely" , "Conjectures, estimates" , "Conjectures, reckons" .)
