<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">calling for</span>' is the definition.<br/ ><span class="explanation-format__explanation">('need' can be a synonym of 'call for')</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for needing that I've seen before include "Eden gin (anag.)" , "Wanting" , "Short of, lacking" , "Requiring" .)
