By the End of This Lesson
- Recognize and pronounce the seven Greek diphthongs
- Understand the iota subscript and what it means for pronunciation
- Read smooth and rough breathing marks correctly
- Know what accents are and how they affect (or don't affect) pronunciation
- Recognize Greek punctuation marks — they differ from English
A Quick Word on Pronunciation Systems
There is no single 'correct' way to pronounce ancient Greek. Three main systems are used in seminaries today:
- Erasmian — devised in the 16th century by Erasmus to give each letter a distinct sound. Used by virtually all English-language seminaries and textbooks. This is what we'll use.
- Modern Greek — how Greek is pronounced today. Many vowels and diphthongs collapse into the 'ee' sound, which makes for easier speaking but harder learning of distinct forms.
- Reconstructed Koine — what the original Koine speakers likely sounded like, as reconstructed by linguists. Used by some specialized programs (e.g. Buth's Living Koine).
The Erasmian system is the de facto standard for first-year Greek in the English-speaking world. Mounce uses it; Black uses it; Croy uses it. We'll use it too.
Diphthongs
A diphthong is two vowels written side-by-side that combine into a single sound. Greek has seven of them. Memorize each pairing as a unit.
| Diphthong | Pronunciation | Like English… | Example |
|---|
| αι | ai | as in 'aisle' | καί (and) |
| ει | ei | as in 'eight' | εἰς (into) |
| οι | oi | as in 'oil' | οἶκος (house) |
| υι | wi | as in 'we' | υἱός (son) |
| αυ | au | as in 'sauerkraut' | αὐτός (he) |
| ευ | eu | 'eh-oo' run together | εὐαγγέλιον (gospel) |
| ου | ou | as in 'soup' | οὐ (not) |
Pattern to notice
Five of the seven diphthongs end in iota (ι): αι, ει, οι, υι. Two end in upsilon (υ): αυ, ευ, ου. The second vowel is what makes it a diphthong; the first vowel determines the starting sound.
Iota Subscript
Sometimes you'll see a tiny iota tucked underneath the letter alpha, eta, or omega:
ᾳ ῃ ῳ
— alpha, eta, omega each with iota subscript —
In ancient Greek these were genuine diphthongs (āi, ēi, ōi). By the Koine period the iota was no longer pronounced; it remained only in the writing as a silent marker. You don't pronounce it, but the grammar still cares it's there — it often signals the dative case, which we'll meet in Lesson 4.
Breathing Marks
Every Greek word that begins with a vowel — and every word that begins with rho (ρ) — carries a breathing mark over its initial letter. There are only two of them.
| Mark | Name | Pronunciation | Example |
|---|
| ἀ | smooth breathing | no extra sound | ἀγάπη (love — say "agápē") |
| ἁ | rough breathing | add an 'h' sound | ἁμαρτία (sin — say "hamartía") |
⚠ This matters
Smooth and rough breathing distinguish completely different words. ἐν (with smooth) means 'in'; ἕν (with rough) means 'one'. ὁ (rough) is 'the'; ὃ (smooth, with grave accent) is 'which/that'. Look at the mark every time.
A few rules to know:
- Every word starting with a vowel has either smooth or rough breathing — never neither.
- Every word starting with upsilon (υ) takes rough breathing. Always. (This is why the English derivatives — 'hyper-', 'hydro-', 'hyper-' — all start with 'h'.)
- Every word starting with rho (ρ) takes rough breathing. So ῥῆμα ('word, saying') is pronounced 'rhēma'. The rh in 'rhetoric' and 'rhythm' is from this.
- For diphthongs, the breathing mark goes over the second letter: οἶκος, not ὄικος.
Accents
Most Greek words also carry an accent mark over one syllable. There are three accent marks:
| Mark | Name | Form | Example |
|---|
| ά | acute | forward slash | λόγος |
| ὰ | grave | backward slash | τὸ ἔργον |
| ᾶ | circumflex | a curved 'roof' | δοῦλος |
Good news
In Erasmian pronunciation, all three accents are read the same way — as a slight stress on that syllable, like English stress. So λόγος is pronounced 'LO-gos' and δοῦλος is 'DOO-los'. The original ancient pitch distinctions are not preserved in modern reading.
The accents do matter for grammar, however — in some cases an accent is the only thing distinguishing two words that look identical. We'll address those when they come up. For now: just stress the syllable that has the accent.
Some practical rules:
- An accent never falls farther from the end than the third-to-last syllable.
- The circumflex only ever falls on a long vowel or diphthong.
- Some short words ('proclitics' and 'enclitics') have no accent at all — they lean on the next or previous word.
- You don't need to memorize accent rules in detail at this stage. Recognize them, stress the marked syllable, and move on.
Punctuation
Greek punctuation is mostly familiar — but two marks are different from English, and one is the same as ours but means something else.
| Mark | Greek | Function | English equivalent |
|---|
| period | . | end of sentence | . |
| comma | , | pause within sentence | , |
| colon / semicolon | · | stronger pause; mid-period | : or ; |
| question mark | ; | question | ? |
⚠ The semicolon trap
A Greek semicolon (;) is what English uses for a question mark. So τίς εἶ; means 'Who are you?' — it ends with a question, despite looking like English's semicolon. Get used to seeing this.
Greek's mid-level pause (which English would write as a colon or semicolon) uses a raised dot: ·. This dot is at letter-cap height, not at the baseline.
Read These Aloud
Now that you have all the tools, sound out these words and phrases carefully. Identify the breathing marks, accents, and diphthongs.
ἐν ἀρχῇ ἦν ὁ λόγος
— en archē ēn ho logos —
"In the beginning was the Word" (John 1:1). Notice: ἐν smooth-breathing 'e'; ἀρχῇ with iota subscript and circumflex; ἦν circumflex on eta; ὁ rough-breathing alone (says 'ho').
υἱὸς θεοῦ
— huios theou —
"Son of God." The diphthong υι combines with the rough breathing on the upsilon (which is automatic) to give 'h-wi'. θεοῦ has a circumflex over the diphthong ου.
ἁμαρτία · ἔργον · ζωή
— hamartia · ergon · zōē —
sin · work · life. Three vocabulary words you'll meet later. Notice the rough breathing on hamartia (with the 'h'), the smooth on ergon, and how zōē is pronounced 'zoh-AY' (omega + eta, not just two e's).
Practice now
Read each example above out loud three times. If a word is unclear, walk through it letter by letter, identifying the breathing mark and the accent. After this lesson you should be able to sound out any Greek word — even ones whose meaning you don't yet know.
