Modifier Letter Small Sideways U

It marks a clipped or transitional reduced-u sound.

The Uralic Phonetic Alphabet (UPA) is a specialist way to write speech sounds, especially for Uralic languages such as Finnish and Hungarian. Its full-sized sideways u, ᴝ, represents a reduced vowel—a less fully pronounced u; superscript ᵙ marks an extremely short or transitional version.

The exact sound depends on the language and analysis. UPA is a transcription convention, not a promise that each use matches a single sound in the International Phonetic Alphabet (IPA), a separate system for writing speech sounds.

Why is ᵙ sideways?

The sideways turn avoids an unreadable full rotation.

The Uralic Phonetic Alphabet, also called Finno-Ugric Transcription (FUT), was first published by Eemil Nestor Setälä in 1901 to record Uralic pronunciation. The notation has been revised since.

In UPA, rotation marks reduced sounds. A fully turned u would be difficult to distinguish from n, so this reduced-u form is rotated a quarter-turn instead.

How do I type ᵙ in plain text?

Use ᵙ itself when the transcription distinction matters.

If an editor offers Unicode hexadecimal input, enter U+1D59 through its code-point command; the key sequence depends on the software.

Font styling on an ordinary u changes its appearance but does not encode ᵙ. Different fonts may draw this glyph differently; the drawing alone does not change its phonetic role.
