U+0470 "Ѱ" Cyrillic Capital Letter Psi Unicode Character
U+0470 "Ѱ" Cyrillic Capital Letter Psi is a historical letter from the early Cyrillic alphabet, directly derived from the Greek letter psi (Ψ, ψ) and used primarily in the writing of Old Church Slavonic and other early Slavic texts. It represented the sound combination /ps/ and was typically employed in words borrowed from Greek, such as those related to religious or philosophical concepts. While it was a standard character in the original Cyrillic script, it gradually fell out of use during the orthographic reforms of the 18th century, being largely replaced by the digraph "пс" in modern Cyrillic spellings. Today, the letter survives mainly in scholarly works, liturgical texts, and as a symbol for mathematical or scientific notations in certain contexts.
