<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">occurring in small stages</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for gradual that I've seen before include "Steady" , "By slow degrees" , "Taking place by degrees, not sudden" , "Happening slowly and by degrees" , "Bit by bit" .)
