En inglés, como en español, la abreviatura de los números ordinales se forma poniendo el número en cifra, seguido de las dos últimas letras de la palabra en forma escrita:
- 1st. - first
- 2nd - second
- 3rd - third
- 30th - thirtieth
Los números ordinales que no contienen al final de la cifra un 1, 2 o 3 se forman añadiendo th al número cardinal:
- Decimocuarto: 14 (Fourteen) - 14th (Fourteenth)
- Trigésimo: 30 (thirty) - 30th (thirtieth)
En el caso de números ordinales compuestos, sólo la última cifra se escribe en forma de número ordinal.
Así:
- 6,210th - Six thousand, two hundred and tenth.
- 321 - Three hundred and twenty-first.
Cuando hablamos de reyes o reinas, los numeros ordinales se escriben en forma de números romanos:
- Isabel II - Isabel the Second
- Henry VIII - Henry the Eighth
