- Iotacism
:"For the
palatalization of certain consonants inSlavic languages , seeiotation ."Iotacism is the process by which a number of
vowel s anddiphthong s inAncient Greek converged theirpronunciation to sound like iota inModern Greek .Instances of iotacism
Ancient Greek had a broader range of vowels (see Ancient Greek phonology) than Modern Greek. Eta (η) was a long
open-mid front unrounded vowel IPA|/ɛː/, andupsilon (υ) was aclose front rounded vowel IPA|/y/. Over the course of time, both of these vowels came to be pronounced like theclose front unrounded vowel iota (ι) IPA| [iː] . In addition, certain diphthongs merged to the same pronunciation, especiallyepsilon -iota (ει) and (later) upsilon-iota (υι) .Issues in textual criticism
Iotacism meant that some words with originally distinct pronunciations were pronounced similarly, which can be seen in some of the variant readings of the
New Testament . The upsilon of ὑμεις "humeis" (or ὑμων "humōn") and the eta of ἡμεις "hēmeis" (or ἡμων "hēmōn") could be easily confused if a lector were reading tocopyist s in ascriptorium . As an example of a relatively minor (almost insignificant) source of "variant readings", some ancientmanuscript s spelled words the way they sounded, such as the 4th-centuryCodex Sinaiticus , which regularly substitutes a plain iota for the epsilon-iota diphthong.See also
