The Origin of Eightteen or Eighteen

To understand why “eighteen” is correct, let’s look at its history.

The word comes from Old English:

“eahta” (meaning eight)
“tīene” (meaning ten)

Over time, these words combined and changed in pronunciation and spelling. Language naturally simplifies words for easier speech. That’s why the extra “t” from “eight” disappeared when forming “eighteen.”

So instead of:

❌ eight + teen = eightteen

It evolved into:

✅ eigh + teen = eighteen

This pattern is common in English. Many number words change slightly when combined.
