Ordinals

Ordinals are numbers that show the position or order of something. They are used to indicate the rank or placement of items in a sequence.

Formation of Ordinals

Ordinals are formed by adding a suffix to the cardinal number. The most common suffixes used to form ordinals are "-st", "-nd", "-rd", and "-th". For example:

• First (1st)
• Second (2nd)
• Third (3rd)
• Fourth (4th)
• Fifth (5th)
• ...

Usage of Ordinals

Ordinals are used in various contexts, such as describing the order of events, ranking items, and indicating the position in a list. For example:

• The first place winner
• The second chapter of a book
• The third day of the week

Comparing Ordinals

When comparing ordinals, the suffixes are not used. Instead, the words "first", "second", "third", etc. are compared directly. For example:

• She finished in first place.
• He came in second, and she was third.

Understanding ordinals is important for understanding the order of items and events in a sequence.
