A in Different Fonts

From an ox’s head to the first letter

A is the oldest letter you will type today with a clear picture behind it. The Phoenician letter aleph meant “ox”, and its early form was a stylised ox head with two horns. The Greeks borrowed it as alpha, turned it on its side and used it for a vowel, because Greek needed vowels and Phoenician (which wrote consonants) had a glottal sound Greek didn’t use. By the time the Romans took it over, the horns had become the two legs of the capital A you know, pointing down.

That rotation is still visible in the turned symbol ∀, which mathematicians use for “for all”. Flip it back and you get the ox horns again.

Two lowercase a’s

Lowercase a comes in two shapes, and the styled alphabets show both:

The single-storey form also exists as its own letter, ɑ (U+0251, Latin alpha), used in phonetics for the vowel in “father”. In handwriting, children are often taught the single-storey a; its cursive version is covered on the cursive A page.

Which styled A to pick

A is a symmetric, pointed letter, so it suits heavy styles well. Some practical notes:

• Bold script 𝓐 / 𝓪: the safest decorative A. Unlike the regular script alphabet, bold script has no letters borrowed from older blocks, so the A sits evenly beside the rest of a name.
• Regular script 𝒜: lighter and more elegant, and A itself is a native math-block character (U+1D49C), so it won’t look out of step. The letters that do look off in script are B, E, F, H, I, L, M, R, e, g and o.
• Bold gothic 𝕬 / 𝖆: the “Old English” look. The capital A in Fraktur is so ornamental that some readers don’t recognise it at small sizes, so test it in your name field first.
• Double-struck 𝔸 / 𝕒: clean and modern; A has no special maths meaning here, unlike ℂ or ℝ.
• Small caps ᴀ: from the Phonetic Extensions block, where it was added for transcribing languages. It reads well in bios.

Tiny A’s

A is one of only 17 letters with a true subscript form: ₐ (U+2090). The superscript set has both cases, ᴬ and ᵃ, so A shrinks cleanly in either direction, which is not true of most of the alphabet.

The emoji A

Black-square 🅰 is the odd one out. Unicode gave four letters an emoji role for blood types (🅰 🅱 🅾 🅿), so many phones turn A into a red tile with rounded corners while 🅲 or 🅳 stay black. If you spell a word in black squares and one letter is red, that’s why. The bubble text generator offers outline circles ⓐ and black circles 🅐 that don’t have this problem.

Look-alike A’s and why they matter

Several scripts contain a character that looks exactly like A:

• А / а: Cyrillic (U+0410 / U+0430)
• Α: Greek capital alpha (U+0391)
• Å: the Angstrom sign (U+212B), a separate code point from the Swedish letter Å, kept for compatibility

To a person these are the same letter; to software they are different. In 2017 a security researcher registered a domain spelled entirely in Cyrillic letters that displayed as “apple.com” in some browsers. Browsers responded by showing mixed or confusable scripts as punycode. The same trick shows up in usernames, which is why many platforms block Cyrillic-in-Latin names. Styled math letters like 𝐀 are different: they fold back to a plain A under Unicode normalization, so a system that normalizes can still read them. See how fancy text works for the details.

How often you’ll type it

A is the third most common letter in English text, at roughly 8.2% of all letters, behind E and T. That frequency is worth remembering when you style a full sentence: an alphabet whose A looks odd will show the flaw everywhere.
