Something like:

           select 'desk' stuff,'is red with glass' description from dual union all
           select 'desk','is rounded' from dual union all
           select 'desk','having four legs' from dual union all
           select 'chair','its color is brown' from dual
select  case row_number() over(partition by stuff order by 1)
          when 1 then stuff || ' ' || description
          else description
        end stuff_description
  from t
  order by stuff desc
STUFF_DESCRIPTION
desk is red with glass
is rounded
having four legs
