In Greek, the pronunciation of particular letters, like eta and upsilon, as iota (ē) due to a frequent sound modification.
A misspelling resulting from such pronunciation.
The regular use of the noise of iota (compared to English e in feel), as one of the modern-day Greeks; in addition, confusion from sounding ε, ι, η, υ, ει, etc., like ι.
Conversion of other vowel sounds into that of iota (English ē); especially, in pronunciation of Greek, the rehearse of offering the noise of iota (ι) and to the vowels η and υ, and the diphthongs ει, ῃ, οι, and υι indiscriminately. This is the rule in contemporary Greek. Also called itacism. In opposition to etacism. Compare lambdacism, rhotacism.
