In addition to that, we will also introduce you some common twelfth synonyms as well. But first, let’s see what the word “twelfth” means before we jump into any further details!

What does twelfth mean?

In the English language, twelfth is an ordinal number, describing a person or a thing in position number twelve of a sequence. It comes right before the thirteenth and next after the eleventh in position. In other words, twelfth is the written form of ordinal number 12th. That’s really similar to the other ordinal numbers like sixth (or 6th), seventh (or 7th), eighth (or 8th), eleventh (or 11th), tenth (or 10th), and so on, right?

For example:

Our next appointment is on the twelfth of July (or on July 12th).

Question: What grade are you in? – Answer: I am in twelfth grade.

Besides, as a noun, “twelfth” means one of 12 equal parts of a whole, as in “This very big pizza was divided into 12 equal parts and each one of us ate a twelfth of it."

Are Twelveth and twelvth also grammatically correct?

“Twelfth” is 12th as a written word, but are the words “twelveth” and “twelvth” the other versions of Twelfth? Do they also mean 12thor not?

In fact, if you search for “twelveth” and “twelvth” on the internet via search engines, like Google, you will find a lot of results for these 2 words. But if you look them up in the standard dictionaries, you won’t find any result. You just can get the word “Twelfth” in those dictionaries for sure. That means both “twelveth” and “twelvth” don’t actually exist in English and they are just spelling mistakes of the word “twelfth”. There is also the opinion supposing that the word twelveth (= twelve + th) itself may be an archaic form of “twelfth”, but we are not sure about that.

In a nutshell, you should always keep in your mind that only “twelfth” is the correct spelling of ordinal number twelve. Other spellings like “twelveth” and “twelvth”are all grammatically incorrect.
