“How to Use Ordinal Numbers in English?”

Ordinal numbers are used to indicate the position or order of something in a series. In English, ordinal numbers are formed by adding the suffix “-th” to cardinal numbers, except for “one” and “two,” which have irregular forms. For example, “first” instead of “oneth,” “second” instead of “twoth.”

Ordinal numbers are commonly used in dates, such as “January 1st” or “December 25th,” and in expressing rankings, such as “the third-best player” or “the 13th chapter.” It is important to note that ordinal numbers are not used with decimals or fractions.

When writing ordinal numbers, it is important to place the suffix “-th” after the number without any spaces or hyphens. For example, “7th” instead of “7-th” or “seventh.” In spoken English, ordinal numbers are pronounced by adding “-th” to the end of the cardinal number, except for “11th,” “12th,” and “13th,” which have their own unique pronunciations.

In conclusion, ordinal numbers are an important part of English grammar and are commonly used in everyday language. By understanding how to use them correctly, you can effectively communicate your ideas and express the order or position of things in a series.
