How to Pronounce Latin: Classical Versus Ecclesiastical

Nobody alive learned Latin from a native speaker, so there is more than one accepted way to pronounce it. Two systems are in common use.

Classical pronunciation

Classical pronunciation is a scholarly reconstruction of how educated Romans spoke around the first century BC. Many schools and universities teach it.

Letter	Classical sound	Example
c	always k	Cicero (KIK-eh-roh), Caesar (KY-sar)
g	always hard, as in "go"	gens, magnus
v	w	veni, vidi, vici (WEH-nee, WEE-dee, WEE-kee)
i (before a vowel)	y	iūs (yoos), Iūlius (YOO-lee-us)
ae	like "eye"	Caesar, aequus
au	like "ow"	aurum
oe	like "oy"	poena
qu	kw	quis
s	always s, never z	rosa

Ecclesiastical pronunciation

This is the pronunciation used in church music and liturgy, shaped by Italian:

Letter	Ecclesiastical sound	Example
c before e, i, ae, oe	ch	caelum (CHAY-loom), Cicero (CHEE-cheh-roh)
v	v	veni (VEH-nee)
ae	like "ay"	caelum
gn	ny	agnus (AH-nyoos)
ti before a vowel	tsi	gratia (GRAH-tsee-ah)

Stress

Stress follows a simple rule in both systems:

1. Two-syllable words are stressed on the first syllable: RO-sa.
2. Longer words are stressed on the second-to-last syllable if it is long: a-MĀ-tis.
3. Otherwise, stress falls on the third-to-last syllable: DO-mi-nus.

A syllable is long if it contains a long vowel or a diphthong, or if it is followed by two consonants.

Which should you use?

• For classics and school courses: classical pronunciation, unless your teacher says otherwise.
• For church music: ecclesiastical pronunciation.
• For reading silently or working with a dictionary: neither is required, but knowing one makes words easier to remember.

Practice phrases

• Carpe diem — KAR-peh DEE-em (classical).
• Ars longa, vita brevis — ARS LON-ga, WEE-ta BREH-wis.

Tips

1. Choose one system and stay consistent.
2. Say long vowels longer, as in rēx and mōs.
3. Use the dictionary to check spellings and macrons.
