Ordinal numerals are a way of expressing numbers as a position in a sequence. They are commonly used in lists, rankings, and other ordered collections.

In English, the ordinal numerals are formed by adding a suffix to the number. For numbers ending in 1, 2, and 3, the suffixes are st, nd, and rd, respectively (with exceptions for 11, 12, and 13). For all other numbers, the suffix is th.

In many other languages, the rules for forming ordinal numerals are different. Some languages have just one suffix, like German or Dutch with te or de, respectively.

The full set of ordinal rules for each locale is defined in the Unicode Common Locale Data Repository (CLDR).
