What are ordinal numbers

Ordinal numbers are numbers that show position or order in a sequence. For example, the words first and twentieth are ordinal numbers, as are numerals with suffixes at the end like 1st and 20th. Ordinal numbers or ordinals are written using numerals as prefixes and adjectives as suffixes. For example, 1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th and so on. We can easily identify an ordinal number: it talks about positioning.
  • Ordinal numbers are numbers that denote position or rank in a sequence. 
  • They are often used to number lists, as in first, second, third, etc. In mathematical terms, ordinal numbers are a special case of the natural numbers (positive integers).
  • There are a few things to keep in mind when using ordinal numbers. 
  • First, they always come after the noun they modify. In other words, you would never say "two people and third a cat." - Second, ordinal numbers are not always written out in full. In many cases, you can use the abbreviations "1st," "2nd," "3rd," etc.

Here are some examples of ordinal numbers in use:

  • She is the third person in line.
  • This is my second time seeing that movie.
  • I will be arriving on the 10th.

As you can see, ordinal numbers are a helpful way to communicate position or rank. When used correctly, they can make your writing more precise and easier to understand.
