Vocabulary of Ordinal Numbers in English
Contents
If you're learning English and want to master counting or arranging items in a sequence, understanding ordinal numbers is key. This guide aims to demystify the concept, equipping you with the right vocabulary and increasing your confidence in using these numbers in daily communication.
What is an Ordinal Number?
An ordinal number denotes the position or order of an item in a list or series, indicating its rank in a sequence rather than the quantity, which is the role of a cardinal number. For instance, if you're looking at a line of people and asked to identify the "5th in words," you would say "fifth." This concept is a cornerstone of numerical vocabulary in English and many other languages.
