Incorrect spelling, explanation: the word eightteen is a mistake because it does not follow the standard orthographic conventions of English and is not a recognized spelling of the number between seventeen and nineteen. In English, numbers between eleven and nineteen are typically formed by combining the base number with the suffix -teen (e.g., thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen). Eightteen deviates from this convention by combining eight with teen but incorrectly forming it as eightteen. Eighteen is the only correct form.

Correct spelling, explanation: eighteen is the widely accepted and standard spelling of the number in English. It is recognized by dictionaries, language authorities, and used in formal and informal contexts. The word eight ends with the sound /t/. When combined with the suffix -teen, which begins with the sound /t/ as well, the pronunciation becomes smoother and more efficient by dropping one of the /t/ sounds. This process, known as consonant cluster reduction or assimilation, is a common phonological phenomenon in English. Eightteen is incorrect because it deviates from these established norms and conventions.
