Ordinal Numbers
Cardinal numbers express quantity: two (2), thirtyfive (35) etc...
Ordinal numbers indicate order or rank: first (1st), second (2nd), third (3rd) etc...
The definite article "the" normally goes in front of an ordinal number: e.g. "Queen Elizabeth the second."
For most ordinal numbers, the ending 'th' is used, with one or two exceptions for those inevitable irregular numbers:
