“z” closes out the lowercase alphabet in more ways than one: it’s the last letter alphabetically, and it’s also one of the letters with the rockiest relationship to Latin itself. At one point, the Romans actually removed it from their alphabet, only to bring it back later out of necessity.

A Short History of “z”

“z” traces back to the Phoenician letter zayin, thought to represent a weapon, possibly an axe, mace, or a specific type of tool, though interpretations vary. The Greeks adopted it as zeta, keeping it in regular use as a standard part of their alphabet for a hard “z” or “dz” sound.

Here’s where “z” takes an unusual detour. Early Latin actually included a version of this letter, inherited through the Etruscans, but at some point during the early development of Latin, Roman grammarians deliberately dropped it from the standard alphabet, since Latin’s own sound system didn’t really need a distinct “z” sound at the time. The letter simply fell out of active use for a stretch of Roman history.

It didn’t stay gone for long, though. As Latin absorbed more and more vocabulary borrowed from Greek, particularly scholarly, technical, and philosophical terms, the need for a dedicated “z” sound resurfaced, since these Greek loanwords used sounds Latin’s existing letters couldn’t represent cleanly. The Romans reintroduced “Z,” borrowing it back from Greek zeta specifically to handle these borrowed words, and placed it at the very end of the alphabet rather than restoring it to any earlier position, a placement that reflects its status as a late reintroduction rather than an original, foundational letter. That end-of-alphabet position has stuck ever since, all the way into the modern English alphabet used today.

Anatomy of a Lowercase “z”

Lowercase “z” is built from a top stroke, a diagonal stroke connecting it to a bottom stroke, forming a shape close to a stylized Z or lightning-bolt silhouette, sitting entirely at x-height with no ascender or descender. Structurally, it shares a loose family resemblance with “s” in that both letters are built around diagonal or curved connective strokes, though “z” relies on straight lines throughout rather than curves.

The angle of the central diagonal stroke is the letter’s primary design variable. A steep, near-vertical diagonal makes “z” feel compact and forceful; a shallower, more horizontal diagonal makes it feel wider and more relaxed. The top and bottom horizontal strokes also need careful balancing in length and weight relative to that diagonal, since an uneven relationship between the three strokes can make the letter look lopsided or unstable.

Some typefaces add a small diagonal cross-stroke through the middle of “z,” a stylistic holdover found in certain historical and European typographic traditions, originally intended to help distinguish “z” from the numeral “2” in handwriting and some early printed contexts, similar in spirit to the disambiguation problem covered earlier in this series with lowercase “l” and its neighbors.

Designing the Letter From Scratch

Because “z” shares some structural logic with “s” — both rely on a central connecting element bridging a top and bottom portion of the letter — designers sometimes reference the stroke weight and general proportions established in “s” when beginning work on “z,” even though the two letters use fundamentally different geometry, straight versus curved.

The central diagonal stroke gets the most direct attention during the design process. Designers test a range of angles, since this single stroke defines much of the letter’s overall character, then balance the top and bottom horizontal strokes against it until the whole shape feels stable and evenly weighted rather than top-heavy or bottom-heavy.

Because “z” is one of the rarest letters in English, designers sometimes have more creative latitude here than with a heavily used letter, and some typefaces use “z” as an opportunity for a small stylistic flourish, such as a slightly curved rather than perfectly straight diagonal, since the letter’s rarity means any such flourish won’t repeat often enough across a page to become visually tiring.

Unique Facts About “z”

“z” is one of the least frequently used letters in written English, similar in rarity to “j,” “q,” and “x,” which is why it holds the highest point value of any letter in games like Scrabble.

The fact that “z” was actually removed from and later reintroduced into the Latin alphabet is a genuinely unusual episode in the letter’s history — most letters in the alphabet have a continuous, unbroken presence once adopted, making “z”‘s brief disappearance and later comeback a rare exception worth noting.

“z” also holds the distinction of being the very last letter in the modern English alphabetical order, a position directly inherited from its status as a late reintroduction in Latin, tacked onto the end rather than restored to wherever it might have originally sat.

“z” in Popular Fonts

In Garamond and other old-style serifs, “z” carries visible calligraphic stress, with the diagonal stroke thickening and thinning the way a broad-nib pen naturally produces, and the top and bottom strokes often finished with small serif details. Helvetica keeps all three strokes evenly weighted and precisely angled, contributing to its clean, mechanically consistent character. Futura pushes the diagonal toward a pure geometric angle, matching the compass-and-ruler design philosophy found throughout the rest of its letterforms.

In script and handwriting fonts, “z” is often given a looping tail or an extended entry stroke, since its naturally angular structure otherwise makes it one of the more difficult letters to integrate smoothly into a flowing cursive baseline.

Summary

Lowercase “z” closes out the alphabet with one of its more turbulent backstories: dropped from Latin entirely at one point, then reintroduced specifically to handle Greek loanwords, and permanently placed at the very end of the alphabet as a mark of its status as a late arrival. Structurally simple but historically eventful, “z” is a fitting final letter for a series that’s shown, again and again, how much history hides behind even the most ordinary-looking shapes.
