The Origin of Ninth

The word ninth comes from Old English nigoða, which later became ninthe and then ninth. Over time, English simplified the spelling and pronunciation.

English often changes word forms instead of following strict patterns. For example:

Number	Ordinal
Five	Fifth
Nine	Ninth
Twelve	Twelfth

The spelling looks irregular, but it follows historical sound changes. The final e in nine was removed to make pronunciation smoother: ninth (not nine-th).

This is why nineth never became a standard spelling.
