What 𝛂 means
It is Greek alpha with its mathematical bold style encoded.
Greek alpha descends from Phoenician aleph, a consonant letter in the alphabet used by the ancient Phoenicians. Greek writers adapted that alphabet by the early eighth century BCE and reassigned aleph to a vowel sound. The earliest surviving Greek inscriptions date to around 760 BCE; they show the old Greek alphabet, not this later bold typeface.
In 1886, Oliver Heaviside described choosing bold type for vectors—quantities with size and direction—after finding Greek and German blackletter hard to read in formulas. That history explains one convention for bold Greek letters, but it does not assign alpha one fixed job.
How is 𝛂 different from α?
Its bold mathematical style is part of the character itself.
Use it when a formula defines alpha in bold mathematical style; the glyph alone supplies no variable name or value. Follow the equation's notation or legend to see what alpha represents.

Questions people ask
2Why does 𝛂 become α?
Compatibility normalization. It can reduce 𝛂 to plain α, erasing the encoded bold distinction. Avoid that normalization when the distinction must survive.
Why does 𝛂 look different in another font?
Font design. Unicode's chart glyph is an identification sample, not a required drawing; mathematical fonts may vary its outline while displaying the same character.
