Ninth vs. Nineth – Which is Correct?
The correct spelling for the ordinal number following eighth is ninth. The spelling “nineth” is a common misspelling and is not considered standard English. Always opt for “ninth” in all contexts, whether formal or informal, to ensure grammatical accuracy.
Ninth or Nineth – Which is Correct?
When referring to the position after eighth, the only correct spelling is “ninth.” The alternative “nineth” is a prevalent error, often arising from phonetic confusion. English ordinal numbers like “fourth,” “fifth,” and “sixth” often involve a “th” suffix, but the base word’s spelling can change, as seen with “nine” becoming “ninth.” People mistakenly add “eth” by analogy with other ordinal numbers or simply because it sounds somewhat similar to “ninth” when spoken quickly.
The Best Trick to Remember the Difference
To remember the correct spelling, think about the base word: NINE. When forming the ordinal, you drop the ‘e’ from “nine” before adding ‘th’. So, NINE – E + TH = NINTH. There is no ‘e’ after the ‘n’ in the correct ordinal form. If you see an ‘e’ after the ‘n’ in the ordinal, it’s incorrect.
| Word | Part of Speech | Meaning | Example |
|---|---|---|---|
| ninth | Adjective, Adverb, Noun | Coming after the eighth in order or sequence; one of nine equal parts. | She finished in ninth place in the race. |
| nineth | Incorrect | A common misspelling of “ninth.” | Incorrect: He lives on the nineth floor. |
How to Use Ninth
“Ninth” is an ordinal number used to indicate position in a sequence, division into equal parts, or as a fraction. It functions primarily as an adjective modifying a noun, but can also act as a noun itself (e.g., “the ninth of a series”) or an adverb (less commonly, e.g., “ninthly”). Its usage is straightforward and consistent across all contexts, from formal academic writing to casual conversation.
Example 1: The ninth chapter of the book was the most exciting.
Example 2: She celebrated her ninth birthday with a large party.
Example 3: The team won their ninth consecutive game, setting a new record.
Etymology of the word Ninth
The word “ninth” derives from Old English nigonthe, which itself comes from nigon (nine) and the suffix -tha (indicating order). Over time, the spelling and pronunciation evolved. The dropping of the ‘e’ from “nine” before adding ‘th’ to form “ninth” is a historical linguistic development, contrasting with other ordinals like “sixth” or “seventh” where the base numeral remains more intact. This particular change makes “ninth” a unique case among some ordinal numbers.
Related Concepts
Understanding these broader grammatical concepts can help clarify why “ninth” is the correct form and why misspellings like “nineth” occur.
- Ordinal Numbers: These are numbers that indicate position or order in a sequence (e.g., first, second, third). They are distinct from cardinal numbers (one, two, three) which denote quantity. “Ninth” is an ordinal number.
- Common Misspellings: Many words are frequently misspelled due to phonetic similarity, confusion with similar-sounding words, or inconsistent spelling rules in English. “Nineth” is a classic example of a phonetic misspelling where the ‘e’ from ‘nine’ is incorrectly retained.

Frequently Asked Questions
Question 1: Why do people often misspell “ninth” as “nineth”?
People often misspell “ninth” as “nineth” due to phonetic confusion and analogy with other ordinal numbers. While “nine” ends with an ‘e’, the standard English rule for forming “ninth” involves dropping that ‘e’ before adding ‘th’. The pronunciation of “ninth” can also sound like it might have an ‘e’ to some speakers, leading to the incorrect spelling.
Question 2: Are there any contexts where “nineth” is acceptable?
No, “nineth” is never an acceptable spelling in standard English. It is always considered a misspelling of “ninth.” Always use “ninth” in all forms of communication.
Question 3: How do other ordinal numbers for numbers ending in ‘e’ work?
For numbers ending in ‘e’ when forming ordinals, the ‘e’ is typically dropped before ‘th’ is added. For example, “five” becomes “fifth,” “twelve” becomes “twelfth,” and “nine” becomes “ninth.” This is a consistent pattern in English ordinal formation, though “first,” “second,” and “third” are irregular.
Conclusion
In the perennial debate of “ninth or nineth,” the answer is unequivocally “ninth.” “Nineth” is a common misspelling that should be avoided in all written communication. Remembering that the ‘e’ from “nine” is dropped before adding ‘th’ can serve as a simple yet effective mnemonic. Mastering correct spellings, especially for frequently used words like ordinal numbers, is crucial for clear and professional communication. Pro Tip: Always double-check ordinal numbers, as their formation can sometimes be tricky and deviate from simple rules, directly impacting your credibility.
