Iotacism is a word that refers to the linguistic phenomenon where the Greek letter iota is pronounced like the vowel sound in the word "me". In IPA phonetic transcription, it is spelled /aɪˈɒtəsɪzəm/ or eye-ah-tuh-siz-uhm. The spelling of this word is derived from the Greek letter iota itself, which is represented by "I" in the English alphabet. The suffix "-ism" indicates that it is a phenomenon or characteristic, so iotacism refers specifically to the tendency to substitute the vowel sound for the iota sound.
Iotacism is a linguistic term that refers to a phenomenon observed in certain dialects or accents where the sound represented by the letter "iota" (i) is pronounced differently. Specifically, iotacism occurs when the "iota" sound is replaced by an "i" sound or a similar vowel sound. This deviation from the standard pronunciation is most commonly found in the Greek language, where the letter "iota" (ι) is typically pronounced as "ee."
In some cases, iotacism can also occur in other languages and dialects, resulting in different vowel sounds being used in place of the "iota" sound. This alteration can manifest itself in various ways, with the "i" sound being the most frequent substitute. However, it is important to note that iotacism does not refer to the mere presence of the letter "iota" in certain words or languages, but rather the pronunciation change associated with it.
Iotacism is considered a phonetic or phonological phenomenon since it involves the alteration of speech sounds. It can contribute to dialectal variations and regional accents. Linguists and language scholars study iotacism to better understand the phonetic characteristics of different varieties of languages and how they evolve over time. By examining iotacism, experts gain insights into the pronunciation features of specific dialects and the historical influences that have shaped their phonetic characteristics.

The word "Iotacism" originated from the Greek letter "iota" (Ι, ι) and its related sound changes in various languages. In ancient Greek, "iota" represented a vowel sound similar to the English "ee" or the "y" in "yacht". Over time, this sound underwent a change in certain dialects of Greek, where it shifted to a different sound, often represented by the letter "eta" (Η, η), which represents the long "e" sound in Greek. This sound change came to be known as "iotacism".
The term "Iotacism" was later adopted in linguistics to describe a specific linguistic phenomenon, wherein the sound represented by "iota" changes into another sound, particularly in the context of vowel shifts. It can also refer to the excessive use or pronunciation of the "i" sound.
