Ninty or Ninety: The Correct Spellings

Remembering how to spell ninety correctly can be made easier with a simple trick: the word nine forms the beginning of ninety, just add '-ty' at the end to indicate the tens place. Keeping in mind that ninety is a combination of 'nine' and 'ty' (a common ending in numerals like twenty, thirty, etc.), can help in recalling the correct spelling.

Ninty is an incorrect spelling of the number that comes after eighty-nine, which is correctly spelled ninety. The difference between the two is that 'ninty' is a misspelling and 'ninety' is the accurate representation of the numeral 90. The correct way to spell the number is n-i-n-e-t-y, which aligns with the way it is pronounced. 'Ninty' is the wrong word simply because it does not adhere to the standard spelling conventions of English numerals. The history of the word ninety can be traced back to Old English 'nigontig', which comes from a Proto-Germanic root that is also the source of the word nine.
