🔍 Explanation:

- Ordinal numbers indicate position or order (e.g., first, second, third...).
- They often end in suffixes: -st (1st), -nd (2nd), -rd (3rd), -th (4th and beyond).
- For numbers like 21st, 22nd, 23rd, the suffix depends on the last digit:
- 21st → twenty-first
- 22nd → twenty-second
- 23rd → twenty-third
- 24th → twenty-fourth
- etc.
- Exceptions: 1st, 2nd, 3rd use special endings; others use -th.
