Type of number (7)
I believe the answer is:
ordinal
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">type of number</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 ordinal that I've seen before include "First, for One" , "It shows your place" , "Of position in series; service book (hist.)" , "First and second, say" , "(Of numbers) first or second, perhaps" .)
