Glagolitic Small Letter Yo

It is a Glagolitic letter with no settled reconstructed sound.

Glagolitic was devised around 863 for Scripture and worship in Old Church Slavonic, an early Slavic language used in church services. The proposed Latin-letter transcriptions for ⱖ are JO, JÖ, and Ö: two begin with a y sound; one has no initial consonant. These are scholarly reconstructions, not a settled modern pronunciation. An encoding proposal cites JO in ISO 6861:1996, a standards-era attestation rather than a first-use date.

Religious Glagolitic manuscripts survive from the 10th–11th-century. Later, eastern Slavic traditions favored the related Cyrillic alphabet, while Croatia developed a square style alongside the round one. Fonts can draw a letter differently in those styles without making it a different character.

What does ⱖ signal when sent alone?

Read it as a script character; context gives it any social meaning.

A specialist may be identifying a letter or discussing its historical reading. Croatian public examples from 2021 show Glagolitic also signaling cultural heritage or belonging for people without specialist knowledge.

By itself, ⱖ does not tell you why the sender chose it. Ask what they meant or read the surrounding text.
