Psilosis

Psilosis (/saɪˈloʊsɪs/) is the sound change in which Greek lost the consonant sound /h/ during antiquity. The term comes from the Greek ψίλωσις psílōsis ("smoothing, thinning out") and is related to the name of the smooth breathing (ψιλή psilḗ), the sign for the absence of initial /h/ in a word. Dialects that have lost /h/ are called psilotic.

The linguistic phenomenon is comparable to that of h-dropping in dialects of Modern English, and to the development by which /h/ was lost in late Latin.

History

The loss of /h/ happened at different times in different dialects of Greek. The eastern Ionic dialects, the Aeolic dialect of Lesbos, as well as the Doric dialects of Crete and Elis, were already psilotic at the beginning of their written record. In Attic, there was widespread variation in popular speech during the classical period, but the formal standard language retained /h/. This variation continued into the Hellenistic Koine. Alexandrine grammarians who codified Greek orthography during the second and first centuries BC, and who, among other things, introduced the signs for the rough and smooth breathings, were still using the distinction between words with and without initial /h/, but were evidently writing at a time when this distinction was no longer natively mastered by many speakers. By the late Roman and early Byzantine period, /h/ had been lost in all forms of the language.
