What are the Ordinal Numbers?

Ordinal Numbers are those numerals which are used in identifying the position of objects or persons. They are also called as positioning numbers. If there is a specified list of persons or objects, then the position of each object or person can be determined by using ordinal numbers. The ordinal numbers can be written using numerals as prefix and adjectives as a suffix, for example, 1st, 2nd, 3rd, 4th, 5th, 6th and so on.


Use of Ordinal Numbers

Ordinal numbers can be used for identifying the position of certain objects or persons from a specified list. For example, we can use ordinal numbers in the following ways;

  • Rita always comes 1st in the class.

  • Raju is standing in the 4th place in the queue. 

  • Ritu came 2nd in the race.

  • The 8th table is reserved.
