Not hollow (5)

Ross

I believe the answer is:

solid

<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">not hollow</span>' is the definition.<br/ ><span class="explanation-format__explanation">('solid' is the opposite to 'hollow')</span><br/ ><br/ >This is the entire clue.<br/ ></span>

(Other definitions for solid that I've seen before include "Firm - three-dimensional" , "Substantial - having three dimensions" , "Three-dimensional shape, not hollow" , "Reliable - substantial - pure" , "Reliable; not hollow" .)

I've seen this clue in the Evening Standard, The Telegraph and the Newsday.
