This research examines the origins and phonemic values of Greek letters χ and ψ in historic alphabets.
Analysis of phonemic sequences associated with Greek letters χ and ψ.
Comparison of Greek, Phoenician, and Phrygian alphabets.
Investigation of letter shapes and their historical variants.
Identified χ associated with both /ks/ and /kh/ depending on the alphabet group.
Established ψ as originally representing /kh/ based on phonetic utilization.
Proposed hypotheses about the evolution of letters and values in different alphabetic traditions.

Abstract

The supplemental letters , and were added to the Greek alphabets after the initial adaptation of the Phoenician alphabet. However, the group of alphabets conventionally known as the red alphabets associated with the phonemic sequence /ks/ and with /kh/, while the dark blue alphabets associated with /kh/ and with /ps/. It is now clear that both the letter shapes 󰎌 and 󰐫 were originally variants of the letter , representing /k/. In addition to the evidence of these variants of letter shapes used for /k/ in the Phoenician alphabet, they are also both used for /k/ in the Phrygian alphabet, which is an early relative of the Greek alphabet. This shows that the original value of must have been /kh/, since this can be explained as the utilisation of a variant sign for a velar stop to represent another velar stop. This recognition allows us to propose plausible hypotheses about the development of the signs and their values in the different groups of alphabets.
