Incorrect spelling

3th

Incorrect spelling, explanation: this form is incorrect, because ordinal numbers short form are created with abbreviations of the actual, spoken form. This means, if we say third, the last two letters are the suffix of the ordinal number: 3rd. -th is the ending of other ordinal numbers, but not all of them. This is the reason why the correct form is 3rd, and not 3th.


Correct spelling

3rd

Correct spelling, explanation: 3rd is the correct form, because the full-written form is third. In ordinal numbers the last two letters are the abbreviation added to a number form, for example first = 1st, fifteenth = 15th. The same rule applies to third, which in short, number, form is written as 3rd. This is why 3th is wrong; it simply doesn’t exist.
