Slow and steady (7)
I believe the answer is:
gradual
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">slow and steady</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for gradual that I've seen before include "Steady" , "Happening slowly and by degrees" , "Progressing by degrees" , "Progressive" , "By easy stages, not sudden or steep" .)
