Understanding English Ordinal Numbers

An ordinal number converter is a handy online tool that helps you transform cardinal numbers (like 1, 2, 3) into their corresponding ordinal forms (like 1st, 2nd, 3rd). Ordinal numbers indicate position in a sequence (e.g., "first place," "second attempt"). While seemingly simple, applying the correct **number suffix** in English has specific rules and important exceptions.

The general rules for **English ordinal numbers** are straightforward:
  • Numbers ending in **1** (except 11) use "st" (e.g., 1st, 21st, 101st).
  • Numbers ending in **2** (except 12) use "nd" (e.g., 2nd, 22nd, 102nd).
  • Numbers ending in **3** (except 13) use "rd" (e.g., 3rd, 23rd, 103rd).
  • All other numbers typically use "th" (e.g., 4th, 10th, 20th, 100th).
However, the crucial **ordinal number exceptions** are for **11, 12, and 13**. Despite ending in 1, 2, or 3, these numbers *always* take the "th" suffix (e.g., **11th**, **12th**, **13th**). Our number suffix generator correctly applies these rules, making it a reliable **grammar tool** for writing and communication.

This free online converter is perfect for students, writers, or anyone needing to quickly and accurately convert integers to their ordinal form. It helps in precise writing and avoids common **ordinal number mistakes**. Use this number to word converter (for suffix) to enhance your writing and ensure correct grammatical usage.
