a term that describes a position within an order, e.g. first, second, third, fourth...twentieth, etc.

the number designating place in an ordered sequence

an assigned number representing where on a relative (qualitative) scale an entity stands

A number which shows order, position, or sequence, such as first or fourth, not a cardinal number

a number resulting from counting and always has to do with order.

Ordinal numbers show order. Some ordinals are first (1st), second (2nd), third (3rd), fourth (4th), fifth (5th), etc.

A number designating the place (as first, second, or third) occupied by an item in an ordered sequence.

A number designating the place occupied by an item in an ordered sequence (e.g., first, second, and third).

A whole number that names the position of an object in sequence. First, second, and third are ordinal numbers.

In set theory, ordinal, ordinal number, and transfinite ordinal number refer to a type of number introduced by Georg Cantor in 1897, to accommodate infinite sequences and to classify sets with certain kinds of order structures on them. Ordinals are an extension of the natural numbers different from integers and from cardinals.
