What 𝝊 means
It is a Greek letter styled for mathematical notation.
As an upsilon variable, it gets its meaning from the writer’s formula. Bold italic styling distinguishes it as a mathematical symbol, but it does not assign a universal quantity.
How did upsilon change through time?
It descends from a letter adapted into Greek.
Greek upsilon traces to Phoenician waw 𐤅, a consonant sign that Greek writers reused for a vowel, helping their alphabet mark vowel sounds. The Phoenician-based Greek alphabet was in use by around 760 BCE, when early inscriptions survive.
In Greek of the Byzantine period, “upsilon” meant “plain u,” distinguishing it from the vowel pair οι after their sounds converged. The mathematical bold italic form carries this Greek letter into formulas as a distinct style.
Technical and formula-bound; the surrounding equation supplies the reading.
Do not infer a vector or fixed value from the type style alone; follow the formula’s definition.

1why did 𝝊 turn into υ
A text normalizer can do that. Unicode’s NFKC and NFKD forms fold mathematical styling into the base Greek letter, so 𝝊 becomes υ and loses its style distinction.
