Sounds, Spelling & Pronunciation
Latin uses a 23-letter alphabet (no J, no W; I and V do double duty as vowels and consonants). Most letters sound roughly like English — but four don't, and they're the ones every beginner mispronounces: c and g are always hard, v sounds like English w, and r is trilled.
So Cicerō is KIH-ke-ro, not SIS-er-oh.
Vowel length matters as much as vowel quality. The macron over ā (vs plain a) marks a vowel held about twice as long — and it decides where the accent lands.
Two-syllable words stress the first; longer words stress the penult if it's heavy, the antepenult if not. That's why amī'cus but do'minus.
The classical Romans wrote no macrons; textbooks add them so you can read aloud without guessing.
If you nail these, the rest of Latin pronunciation is mostly intuitive.
Cicerō = KIH-ke-ro (not SIS-er-oh); vīnum = WEE-noom (not VEE-num)
See It In Action
— Verg. Aen. i. 1
Read aloud: WIR-um-kwe, KA-no, TROY-yai. The famous opening sounds totally different from school-Latin if you hard the c and turn v into w.
— B. G. i. 1
Gallia est — three syllables, stress on the FIRST (Gal'-li-a) because the penult li is light. The macrons on dīvīsa tell you which vowels get held.
— Suet. Iul. 37
The most quoted Latin line in English. In classical Latin: WAY-nee, WEE-dee, WEE-kee — not VEE-nee, VEE-dee, VEE-chee. Every vowel here is long.
— Cic. Cat. i. 1
Catilīna — penult lī is long (macron), so accent lands there: ka-ti-LEE-na. The classical c is hard everywhere; medieval Italian gave us "Cha-ti-LEE-na" but Cicero said KA-ti-LEE-na.
Mark every long vowel — they decide accent and add half-beats of length.
amī'cus — long ī makes the penult heavy → stress there
One consonant between vowels goes with the next vowel; doubled consonants split.
pa-ter (open + close), mit-tō (closed + open)
Heavy = long vowel, diphthong, or short vowel + 2 consonants. Light = anything else.
con-tin'-git (penult heavy by position) vs do'-mi-nus (penult light)
Two syllables → first. Longer → heavy penult or, failing that, antepenult.
Rō'-ma, amī'-cus, do'-mi-nus
Two living traditions exist. Classical (the standard for AP and almost all U.S. classrooms) reconstructs the Latin of Cicero's time; Ecclesiastical (Church Latin) follows medieval Italian.
Cicero's pronunciation, ca. 50 B.C.
Cicerō, caelum, agnus
KIH-ke-ro, KAI-lum, AG-nus
Medieval Italian-flavored Latin
Cicerō, caelum, agnus
CHEE-che-ro, CHAY-lum, AHN-yus
Tip: Ask: is c before e/i hard or soft? Classical = always K. Ecclesiastical = CH (as in 'church'). When in doubt for AP Latin, go classical.

Study Tips
- •Drill the four traps first: c = K (always), g = hard G, v = W, r trilled. Once those are automatic, the rest is mostly intuitive.
- •When you see a macron, hold the vowel longer — don't change its quality. ā is still 'ah' (as in 'father'), just slower than short a.
- •For accent: count syllables from the END. Penult heavy → stress penult. Penult light → stress antepenult. Two syllables → always stress the first.
- •Don't worry about ecclesiastical (Church) pronunciation unless your teacher uses it. Classical is the AP standard.
