Greek Subscript Chi

107/128

ᵪ is a lowered chi used in Uralic phonetic transcription to mark influence from a neighboring sound. Eemil Nestor Setälä first published the Uralic Phonetic Alphabet (UPA) in 1901 to record pronunciation in Uralic languages.

Text symbol

What ᵪ means

It marks co-articulation: neighboring sounds shape one another. In UPA, the lowered position records how a neighboring sound affects the sound marked with chi. The system also helps record pronunciation, study sound patterns, and trace word histories in the Uralic language family.

ᵪ is encoded as its own character, so plain text can retain the phonetic distinction. The raised modifier-letter chi, ᵡ, is its superscript counterpart; in UPA, raised and lowered positions carry different phonetic information.

A specialist character in Uralic phonetic notation.

Why does ᵪ show as a box on some devices?

Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
