linear b syllable b010 u

Linear B syllable U

𐀄 writes the vowel-only syllable u in Linear B; by itself, it is not a whole word. Linear B was a Bronze Age script for Mycenaean Greek, an early form of Greek, used on palace tablets to track goods, work, and offerings. Today people use it in historical study and transcription; a font without support may show a square.

What 𐀄 means

It writes the vowel-only syllable u. The Linear B syllabogram U has no consonant before or after its vowel, making it an open syllable. On its own, it is not a complete word; read it with neighboring signs and spelling conventions to work out a Mycenaean Greek word.

Linear B was a palace record system for Mycenaean Greek, an early form of Greek. Its clay tablets tracked goods, workers, deliveries, and offerings. The earliest evidence is associated with Knossos around 1450 BCE; most surviving tablets date to the 13th century BCE.

Linear B adapted many signs from Linear A, a related script. Later Cypriot syllabaries probably descend from the broader Linear A tradition, so these scripts are historically connected but not interchangeable. After the Bronze Age, Linear B's palace role ended; today 𐀄 appears in historical study and transcription.

Why does 𐀄 show as a box?

A font without Linear B coverage cannot draw it. Unicode identifies the character, but fonts supply its visible shape. A square usually means the selected font has no glyph for it; fonts that do support it may draw it differently.

Historical and technical: it belongs in notes about Linear B, not ordinary chat.

Treating it as a complete word loses its one-syllable reading.

Is 𐀄 a Greek letter?

No. Linear B used it to write Mycenaean Greek; it belongs to that earlier syllabary, not the later Greek alphabet.

Why does my Linear B font show 𐀄 as a square?

Usually the font lacks a glyph for this character. A font with Linear B coverage can display it; another font may draw its shape differently.
