Forty-five vs. Fourty five – Which is Correct?
The correct spelling is forty-five. The variant “fourty five” is a common misspelling and should be avoided in all written contexts. Understanding the correct numerical spelling is essential for clear communication and maintaining professional credibility in writing.
Forty-five or Fourty five – Which is Correct?
The distinction between “forty-five” and “fourty five” is straightforward: forty-five is the universally accepted and correct spelling for the number 45. “Fourty five” is an incorrect spelling, likely stemming from a phonetic misunderstanding or an overgeneralization of the “four” spelling. While “four” includes a ‘u’, the number forty (and by extension, forty-five) drops the ‘u’.
The Best Trick to Remember the Difference
To remember that “forty-five” is correct, focus on the base word “forty.” A simple trick is to recall that when you count by tens, the word “forty” is unique because it’s the only one that drops the ‘u’ from its single-digit counterpart (“four”). Think: “Forty has no ‘u’.” This mnemonic helps reinforce that “forty-five” should also not contain the ‘u’.

Etymology of the word Forty-five
The word “forty-five” is a combination of “forty” and “five.” “Forty” comes from Old English feowertig, meaning ‘four tens’. Over time, the spelling evolved, with the ‘u’ being dropped from the ‘four’ component to form ‘forty’ by the 17th century. The ‘five’ component originates from Proto-Germanic *fimf, which also traces back to Proto-Indo-European *penkʷe. The hyphenation for compound numbers like “forty-five” became standard practice to denote them as a single numerical concept.
