The Greek Alphabet

These are the usual forms of the Greek letters. Just like the Roman alphabet, Greek letters may go either above or below the line.

The last column shows the letters inline with alpha. The position of a letter is just as important as its shape. In English, you would never confuse "l" (ell) with "j" (jay), no matter how flyspecky or damaged they are, because one goes up and the other one goes down. And you can tell apart capital/lower-case pairs like Oo and Ss by their size. It is the same with Greek.

If you find a letter that doesn't look like any of the above, see below under variant forms and ligatures.


The form σ Sigma1 lc.png is used only non-finally (beginning or middle of a word). The form ς Sigma2 lc.png is used only at the end of a word. If you come across the latter form at the beginning or in the middle of a word, refer to the double letters section below.

Letters with Multiple Transliterations

The two letters γ (gamma) and υ (upsilon) may be transliterated different ways, depending on the context.


The letter γ (gamma) is usually transliterated as g, but n is used instead when it occurs before certain letters:

Greek Transliteration
γγ ng
γκ nk
γξ nx
γχ nch


The letter υ (upsilon) can be transliterated as either u or y. Generally, if upsilon follows another vowel, use "u". Otherwise, use "y". (For those who can recognise diphthongs: use "u" in diphthongs, "y" elsewhere.) This isn't required, though; you can use u everywhere if you want, but check with the Project Manager to make sure it's done consistently throughout the project.

Capital Letters

Notice how many of the capital letters look just like the equivalent Roman letter:

A, B, E, Z, I, K, L, M, N, O, T, Y.

You can almost always tell from the context if it's supposed to be Greek.

A few others look like their lower-case forms:

Theta Theta uc.png
Theta lc.png
In some fonts, capital theta has a free-floating middle bar. In others, it looks just like a rounder, fatter lower-case theta.
Phi Phi uc.png
Phi lc.png
Some fonts have an unusually big lower-case phi that looks like a capital letter. If they're all the same, assume it is lower-case.
Chi Chi uc.png
Chi lc.png
For all three end-of-alphabet double letters—phi, chi and psi—the main difference between the capital and lower-case letter is its position on the line: above or below.
Psi Psi uc.png
Psi lc.png

In these examples you can see other common differences: in printed Greek fonts, capital letters tend to have serifs, while lower-case letters rarely do; and while lower-case letters are commonly mildly italic, capitals are usually bolt upright.

Watch out for:

H Eta uc.png Eta not H but Ê
P Rho uc.png Rho not P but Rh or RH
X Chi uc.png Chi not X but Ch or CH

Diacritical Marks

Diacritical marks (diacritics) are anything attached to the “main” letter, like an accent é, tilde ñ or cedilla ç. Greek has four basic types:

Example Picture Name Where found
ἁ ἀ Greek breathing only.png breathing mark initial vowel or diphthong, and most ρ (rho, r).
ϋ Greek dieresis.png dieresis
rare: υ (upsilon u) or ι (iota i) following another vowel
Greek iota sub.png iota subscript only with α (alpha a), η (eta ê), ω (omega ô)
ὰ ά ᾶ Greek accents only.png accent any vowel or diphthong

Unless otherwise specified, in transcription all diacritics in Greek text are reproduced. In transliteration only the "rough breathing" is recorded.

Watch out! Greek diphthongs (two vowels together) are always treated as a package, so when you have two adjoining vowels (αι, αυ, ει, ευ, οι, ου; ηυ & υι), the diacritic will appear on the second vowel, but the h for a rough breathing mark will go before the first vowel in the transliteration. (If you should meet αυι, ευι, ουι or ηυι then the 1st pair will be the diphthong and the ι will be single.)

A single vowel can carry as many as three diacritics: breathing mark and accent and iota subscript. If a letter has both an accent and a breathing mark, the accent will be either above or to the right of the breathing. One you may really meet is the word

Greek all three.png

transliterated [Greek: hô]. <Warning: In fonts where the circumflex form of the accent is used, this can be difficult to distinguish from the simple phi φ.> Similarly, dieresis may be combined with an accent; the accent will then be perched on top of the dieresis.

Breathing marks

The “breathing mark” is the Greek way of writing the letter h. The two forms are

“rough breathing” (curls to the right, like a C: Roughbr.png)
“smooth breathing“ (curls to the left, like a comma: Smoothbr.png)

Except for ῥ (rho r) you will normally only see a breathing mark at the beginning of a word.

Smooth Breathing

Smooth breathing Smoothbr.png means “This word does not begin with an h sound”, so it is ignored in transliteration.

Rough Breathing on Vowels

Rough breathing Roughbr.png is transliterated as h before the letter, with these exceptions:

  • If the word begins with a diphthong, the breathing mark will appear over the second vowel, but the h for rough breathing goes at the very beginning of the word. If your transliteration has something like ohu (h between two vowels), you have made a mistake.
  • Exception to the exception: a word printed in all capitals will often have the breathing printed at the beginning even if it starts with a diphthong.
  • If a word begins with a capitalized vowel, the accents and breathing marks are often printed to the left of the letter, rather than above it. If it has rough breathing, make the vowel lower case and capitalize the H: hÊraklês becomes Hêraklês.

In Greek, as in English, there are plenty of word pairs where the only difference is the initial h sound. For example, these two words:

Rough smooth breathing.png

would be transliterated as [Greek: hodous] and [Greek: odous], respectively.

Rough Breathing on Rho

If a word begins with rho, it always has rough breathing, with the rho transliterated as "rh". Note that the "h" goes after the rho, rather than before as with vowels. English words like “rhyme“ and “rhombus” may help you remember this rule.

Double rho in the middle of a word always has rough breathing on the second rho, so διαρροια should be transliterated as diarrhoia. Do this even if the breathing mark is omitted in the printed text.


This is the same diacritic you see in English words such as “coöperate“ or “reënter”. It means that two letters you would normally treat as a diphthong (in English, more often a “long” vowel) should be read as two separate syllables.

You are not required to transliterate dieresis. But the characters ü and ï are in the Latin-1 character set, and will never conflict with anything else in the transliteration, so you may as well include it.

Iota Subscript

This is simply the letter ι (iota i) tucked under a long vowel (alpha, eta, omega). In general, iota subscript is ignored in transliteration.

Some proofers enjoy hunting down iota subscript and including it in their transliteration as plain i. If you want to do this, get the Project Manager’s permission. Conversely, ask the Project Manager what to do about iota subscripts added in earlier rounds.


Greek uses the same accents you see in modern European languages such as French: acute á, grave à and circumflex â. In most Greek fonts, the circumflex looks more like a tilde than the usual “hat” form, but it really is a circumflex.

Unless the Project Comments say otherwise, accents are not recorded during transliteration.

In some projects, the Project Comments will explicitly ask for all accents to be preserved. The system most often used at DP is a hybrid of our ordinary transliteration scheme and Beta code; see the Marking Accents page for details.

An Example

This Greek phrase:


would be transcribed thus:

 ὃτι τῶν φύσει ἡ πόλις ἐστὶ, καὶ

In transliteration, as there are rough breathing marks in the first and fourth words, the letter "h" is added to the start of those words, and all other diacritics are ignored. This phrase would be transliterated:

 [Greek: hoti tôn physei hê polis esti, kai]

For the Terminally Inquisitive

With rare exceptions, each Greek word contains exactly one accent, and it will be on one of the last three syllables. (There are a few very rare exceptions to this.) The grave and acute accent are really the same thing, so you will never see a grave accent in mid-word.

The form ῥ (rh-) is not an orthographic quirk; it reflects the history of the language. Almost all Greek words in ρ started out as sr- which eventually morphed into hr- and then rh-.

Iota subscript originated for obscure historical reasons. Some modern texts have reverted to putting it inline--αι, ηι, ωι instead of ᾳ, ῃ, ῳ--but you will never see this in DP-vintage books.


Punctuation marks in Greek should be transcribed or transliterated along with the letters. Two of them are exactly the same as in English: the period and the comma. Note that Greek doesn't automatically put a capital letter at the beginning of a sentence, though names are usually capitalized.

Two other punctuation marks are different from English:

  • A Greek question mark looks like a semicolon ;, and is transliterated as a question mark ?[4]
  • The medium stop is a single raised dot·, much like the familiar mid-dot · It is transliterated as an English semicolon ; unless you happen to know that a colon : is more appropriate.


The apostrophes at the ends of some words are, in fact, apostrophes, and serve the same purpose that they do in English: The author is leavin' some letters off the ends o' words. Please include the apostrophes in your transcription or transliteration, keeping the space between words. These are not contractions.

Apostrophes are also used to indicate numerals. If the Greek seems unpronounceable and the "word" ends with an apostrophe, you're probably dealing with numerals (for example, ρκ' = 120, σιη' = 218). Refer to Wikipedia's article on Greek numerals. Please proof them as they appear on the page, not as the corresponding number.

Transliteration markup around punctuation

Inside or Outside?

If a bit of Greek ends with a period, does it go inside or outside the markup? Use the same guidelines as for formatting: if the passage is a full sentence, or if it's an abbreviated word, put the period inside the [Greek: ] tags. You may think you can't possibly tell if a Greek word is an abbreviation, but most of them are names of texts, so they will be followed by numbers. If it says something like

Hesiod, Ἀσπ. 574

it's an abbreviation, and becomes [Greek: Asp.] 574. Another common one is


which is Greek for etc.--period and all.

Question mark or semicolon?

If you meet a ; at the end of a Greek passage, how can you tell if it's a Greek question mark or an English semicolon? Well, sometimes you can't. But your best guide is the surrounding English (or at least non-Greek) text. If it's a new sentence, the ; was a question mark and in a transliterated version goes inside the [Greek: ] tags. If the text carries on from mid-sentence, the ; was a semicolon and belongs with the English.

Common errors

  • Putting an 'h' before every letter with an accent, instead of just those with rough breathing. See Diacritical Marks above for how to tell them apart.
  • Confusion between kappa (κ) and chi (χ). They both often look like an x. Chi is larger, and both of its "legs" always drop down below the line. Kappa is usually much smaller, and only drops below the line in older texts, where its right leg may curl under the next one or two letters.
  • Misreadings between nu (ν), omicron (ο), alpha (α), and upsilon (υ). Nu has a sharp point at the bottom, while upsilon is rounded. Upsilon may be nearly closed at the top, but there should be a little gap, while omicron is a full circle. When the top of the alpha is missing (due to imperfect printing, etc.) it can be distinguished from the upsilon by its lower-right tail; also, the alpha usually has a flat line on the right and a curve on the left, the upsilon is the reverse.
  • Confusing a breathing mark with an acute or grave accent. Breathing marks are curved; the accents are straight.
  • Omitted punctuation. In focusing your attention on the letters, it's easy not to notice that there are also punctuation marks in the Greek text. This happens most often with a period or comma at the end of the Greek text. Check to be sure that all the punctuation is present in the proofread version.


  • Greek words can only end with a vowel, or with nu (ν), sigma (ς) or rho (ρ). Careful! "Sigma" includes the compound letters psi (p+s=ψ) and xi (k+s=ξ). There are a few exceptions but they only apply to some very short words that you'll get used to seeing. An apostrophe means there was a vowel, but it's hiding, so all bets are off.
  • If a word ends in th' or ch' or ph' (θ, χ, φ with apostrophe) the next word will almost always have rough breathing.
  • You will never see a word starting with [u] or [y] (upsilon υ with smooth breathing). Unless the text leads you to expect mention of pickle jars [urchê].
  • There is no such word as [os] (ος with smooth breathing).
  • There is no such word as [chata] (χατα with a chi), or [chai] (χαι ditto).
  • If the one-letter word ω (ᾧ) has iota subscript, it's got rough breathing. If it doesn't (ὦ), it's got smooth breathing.
  • You will never see the word [ôs] (ως with smooth breathing). Unless the text leads you to expect the Doric dialectal word for "ear".

Latin is Your Friend

Some Greek words made their way into classical Latin, and many more Greek words were used to make technical, scientific and medical Latin. When you have the Latin, you can often figure out what the Greek ought to be. Details and examples are on the Latin is Your Friend sub-page.

Older and Obscure Items

If Greek makes you unhappy, stop right here. DP expects you to handle basic Greek with the help of the available tools and Greek How-To. You don't have to struggle with the whole Greek spectrum, from unusual letterforms to cryptic ligatures to decorative-but-illegible squiggles. A simple [**indecipherable Greek] and a post to the project thread will do. But if you want to delve deeper, read on.

Two Double Letters

This form of sigma: ς normally only occurs at the end of a word. If you meet one in the middle of a word, it's almost always a letter called "stigma" and the top bit of it usually extends further to the right: ϛ. It gets transliterated as st.

Ou lig.png This letter is a shorthand way of writing ου (transliterated ou). Think of it as υ (upsilon) balanced on top of ο (omicron).

Variant Forms

Here are some common variant forms. Each one is shown between alphas so you can see where the letter goes in relation to the overall line:

Var gamma.png gamma γ g
Var kappa.png kappa κ k
Var pi.png pi π p
Var rho.png rho ρ r
Var tau.png tau τ t
Var Sigma.png (Lunate) Capital Sigma Σ S


Unless you are familiar with the Ancient Greek language, please do not attempt to process words containing the ligatures discussed here. Instead, post to the appropriate Greek Help thread.

In older books, printed Greek used a lot of ligatures. These are groups of letters joined together or abbreviated, rather than being written separately. Two of the most common ones, the double letters mentioned above, lasted until well into the 19th century, so you will meet them in almost all Greek texts.

Ligatures originated with scribal (hand-written) Greek as a way of abbreviating common letter sequences. Latin did the same thing. But unlike Latin, which got rid of almost all its abbreviations soon after printing was developed, Greek held on to the ligatures until the 18th century.
