Designing for the World: Type Beyond the Latin Alphabet

The Latin alphabet you're reading right now has just 26 letters. But global type designers must also design for Arabic's connected, cursive letters, Chinese's tens of thousands of characters, and Devanagari's shared horizontal line called the shirorekha. Designing type for the world's roughly 7,000 languages and dozens of writing systems is one of the hardest, and most interesting, problems in graphic design.

• How to identify different categories of writing systems: alphabetic, abjad, abugida, and logographic • Why letterforms and directionality create design challenges across scripts • Key vocabulary: script, glyph, ligature, and bidirectional text • How real typeface families solve multi-script design problems

An alphabetic script, like Latin, Cyrillic, or Greek, uses separate symbols for consonants and vowels. An abjad, like Arabic or Hebrew, is written mostly with consonants, reads right-to-left, and its letters change shape depending on whether they appear at the start, middle, or end of a word. An abugida, like Devanagari (used to write Hindi), builds each character from a consonant plus a default vowel sound, with the letters hanging from a shared horizontal line called the shirorekha. A logographic system, like Chinese hanzi, has no alphabet at all — instead, tens of thousands of individual characters each represent a whole word or idea.

In Arabic, a single letter can look different depending on where it sits in a word. The letter "ain," for example, has an isolated form, an initial form, a medial form, and a final form — four distinct shapes for one letter. This means a working Arabic typeface needs many more glyphs than its letter count would suggest, plus rules for how letters connect to their neighbors. Designers call these connecting shapes ligatures, and building them convincingly is one of the most technical parts of designing an Arabic typeface.

Latin and Cyrillic read left-to-right, Arabic and Hebrew read right-to-left, and traditional Chinese and Japanese can be set vertically. This becomes especially tricky when scripts mix on the same page, such as an English brand name sitting inside an Arabic sentence. Designers call this bidirectional text, or "bidi" for short, and it requires special rules so the reading order stays correct even though the two scripts flow in opposite directions.
