**What Are Ordinal Numbers?**

It is known that ordinal numbers are the kinds of words that are actually used to put things in order that can be anything from an address to the position a runner finishes in a race. They represent position or rank in a sequential order and also show position or order in relation to other numbers.

The ordinal numbers always have a suffix attached onto the end and the order can be of importance, chronology, size and others. Moreover, the ordinal numbers actually differ from cardinal numbers which represent quantity and other types of numerals.

Based on traditional grammar, all numerals including ordinal numbers may be grouped into a separate part of speech. Based on modern interpretations of English grammar, the ordinal numbers are basically conflated with adjectives.

With the suffix playing as an ordinal indicator, the ordinal numbers will be written in English with numerals and letter suffixes, including 1st, 2nd or 2d, 3rd or 3d, 4th, 11th, 21st, 101st, 477th, etc.

Based on American Sign Language, the ordinal numbers first through ninth are actually made with handshapes similar to those for corresponding cardinal numbers with the addition of a small twist of the twist.

Additionally, there are several rules to determine which suffix to add to a number, including:

- When a number ends with 1, the suffix at the end is -st (1st)
- When a number ends with 2, the suffix at the end is -nd (2nd)
- When a number ends with 3, the suffix at the end is -rd (3rd)
- When a number that ends with 0,4,5,6,7,8,9 the suffix at the end is -th (4th) including 10th, 100th, etc.
- An exception to the rules above us when a numeral ends with 11, 12, or 13 that all use the -th suffix.

Of course, those rules may make it simpler for you to determine which suffix you should turn a cardinal number into an ordinal one.
