From the altar to the page — getting started in the language of the Church.
Pater noster, qui es in caelis…
Michelangelo, the dome of St Peter’s Basilica (1547–1590), Vatican City — its cupola mosaics designed by Cavaliere d’Arpino
“Latin, preserved for posterity, proved to be a bond of unity for the Christian peoples of Europe.”
Pope John XXIII · Veterum Sapientia, 1962
How to Use This Primer
This primer is for the Catholic who wants to understand the Latin Mass, pray the Church’s ancient prayers with comprehension, and begin reading the language of two thousand years of Catholic tradition. No prior knowledge of Latin is assumed.
Each lesson builds on the last. Work through them in order, memorize the vocabulary, and practise on the prayers you already know by heart — you have been saying Latin for years without being told so.
Follow the MassRead the Ordinary in Latin and know what every response means.
Pray with understandingSay the Pater Noster, Ave María, and Credo in the Church’s own words.
Read the VulgateParse simple verses of St Jerome’s Bible word by word.
Build furtherOpen any standard Latin grammar without being lost on the first page.
Before grammar, the ear. Latin is spoken exactly as it is written, and there is nothing in it you cannot already pronounce.
Lesson 1
The Alphabet and Pronunciation
The Latin alphabet has 23 letters — there is no W, and J and U are later additions standing in for I and V. For our purposes we use the full modern alphabet as it is printed in Catholic missals.
Vowels each has one sound, always
Latin vowels are pure. They do not glide the way English vowels do; each has one consistent sound wherever it appears.
Letter
Ecclesiastical sound
Example
Meaning
A
“ah” as in father
grátia
grace
E
“eh” as in bed
Deus
God
I
“ee” as in feet
in
in
O
“oh” as in go
Dóminus
Lord
U
“oo” as in food
unus
one
Diphthongs two vowels, one sound
Diphthong

Example
Meaning
ae
“ay” as in day
caelum

oe
“ay” — the same as ae
poena
punishment
au
“ow” as in how
laudámus
we praise
Consonants where Latin parts company with English
Most consonants are pronounced as in English. These are the exceptions that matter.
Letter or group
Ecclesiastical sound
Example
Note
C before e, i, ae, oe
“ch” as in church
caelum = “CHAY-loom”
The key rule
C elsewhere
“k”
corpus = “KOR-poos”
G before e, i
soft “j”
Regina = “Reh-JEE-nah”
G elsewhere
hard “g”
grátia = “GRAH-tsyah”
SC before e, i
“sh”
ascéndit = “ah-SHEN-dit”
TI before a vowel
“tsee”
grátia = “GRAH-tsyah”
See the exception below
GN
“ny”
Agnus = “AH-nyoos”
V
“v” — as in English
verbum = “VEHR-boom”
H
silent, or nearly so
homo = “OH-moh”
R
slightly rolled
Rex
Stress where the weight of the word falls
In a word of two syllables, always stress the first: Dó-mi-nus, Pá-ter.
In a word of three or more syllables, stress the second-to-last if it is “long” — that is, if it contains a long vowel or is followed by two consonants. Otherwise stress the third-to-last.
For now, let the accent marks in your missal and in this primer guide you: grátia, Dóminus, benedíctus.
Practice read these aloud before you translate them

Part II
Grammar Essentials
Eight short lessons. Latin puts its grammar on the ends of its words, so learning the endings is learning the language.
Lesson 2
How Latin Works — The Cases
The most important thing to understand about Latin is that word order is flexible, because the ending of a word tells you its role in the sentence. Those endings are called cases.
English uses word order to carry meaning: “The Lord loves the soul” is not the same sentence as “The soul loves the Lord.”
Latin uses case endings instead. Dóminus ámat ánimam and Ánimam ámat Dóminus both mean “The Lord loves the soul.” The ending -am on ánimam marks it as the object wherever it stands in the line.
The six cases
Case
Role
English equivalent
Nominative
Subject — who or what does the action
“the Lord” — Dóminus
Genitive
Possession — of, belonging to
“of the Lord” — Dómini
Dative
Indirect object — to, for
“to the Lord” — Dómino
Accusative
Direct object — receives the action
“the Lord” — Dóminum
Ablative
Means, manner, place, accompaniment
“by, with, from the Lord” — Dómino
Vocative
Direct address
“O Lord!” — Dómine
Lesson 3
First Declension Nouns
mostly feminine, base ending -a
The First Declension holds mostly feminine nouns, and they are among the commonest words in Catholic Latin: ánima (soul), écclesia (church), María, grátia (grace), víta (life), glória (glory), via (way).
Pattern: via way, road — feminine, fully regular

A special case: ánima soul
Ánima — as in the Anima Christi — follows via in the singular, but takes the older ending -ábus in the dative and ablative plural: animábus. The odd form keeps it distinct from ánimis, which belongs to the masculine noun ánimus (mind, spirit). Only a handful of nouns do this (fília → filiábus, dea → deábus); do not generalize -ábus to the rest of the declension.
* Special form; the regular ending would be ánimis.

A short box: the fourth declension -us, genitive -ūs
A small declension, but an important one. Its nouns end in -us like Dóminus, yet their genitive singular ends in -ūs with a long u, and — crucially for prayer — their dative singular ends in -ui. Two of the most frequent words in Catholic Latin belong here.

Lesson 5
Third Declension Nouns

Adjectives
agreement in gender, number, and case
A Latin adjective must agree with the noun it modifies in gender, number, and case. Nothing else is required of it — and nothing less is permitted.
First and second declension adjectives -us / -a / -um
The commonest type. The masculine follows the second declension, the feminine the first, and the neuter the second neuter.

Prayer 4
The Glory Be
Glória Patri
Glória Patri, et Fílio, et Spirítui Sancto.
Sicut erat in princípio, et nunc et semper, et in saécula saeculórum. Amen.
In EnglishGlory be to the Father, and to the Son, and to the Holy Spirit. As it was in the beginning, is now, and ever shall be, world without end. Amen.
Key grammar
Glória—glory — nominative: “glory [be]”
Patri, Fílio, Spirítui Sancto—all three in the dative: glory to the Father, to the Son, to the Holy Spirit. Note Spirítui — the fourth-declension dative from Lesson 4, not Spírito
sicut erat—just as it was — erat is the imperfect of esse
in princípio—in the beginning — compare Genesis 1:1 and John 1:1 in the Vulgate: In princípio erat Verbum
nunc et semper—now and always
in saécula saeculórum—into ages of ages — forever and ever
Prayer 5
The Confíteor
I confess
The Confíteor is prayed at the beginning of Mass. The traditional (1962) form is given here; the modern Roman Missal uses a shorter version, noted below.
Confíteor Deo omnipoténti, beátae Maríae semper Vírgini, beáto Michaéli Archángelo, beáto Ioánni Baptístae, sanctis Apóstolis Petro et Paulo, ómnibus Sanctis, et vobis, fratres: quia peccávi nimis cogitatióne, verbo et ópere: mea culpa, mea culpa, mea máxima culpa.
Ídeo precor beátam Maríam semper Vírginem, beátum Michaélem Archángelum, beátum Ioánnem Baptístam, sanctos Apóstolos Petrum et Paulum, omnes Sanctos, et vos, fratres, oráre pro me ad Dóminum Deum nostrum.
In EnglishI confess to almighty God, to blessed Mary ever-Virgin, to blessed Michael the Archangel, to blessed John the Baptist, to the holy Apostles Peter and Paul, to all the Saints, and to you, brethren, that I have sinned exceedingly in thought, word, and deed: through my fault, through my fault, through my most grievous fault. Therefore I beseech blessed Mary ever-Virgin, blessed Michael the Archangel, blessed John the Baptist, the holy Apostles Peter and Paul, all the Saints, and you, brethren, to pray for me to the Lord our God.
Selected grammar
Confíteor—I confess — first person singular of confitéri, a deponent verb: passive in form, active in meaning
Deo omnipoténti—to almighty God — dative, the one confessed to; omnipoténti agrees with Deo
beátae Maríae semper Vírgini—to blessed Mary ever-Virgin — every word dative
quia peccávi—that I have sinned — peccávi is the perfect tense
cogitatióne, verbo et ópere—in thought, word, and deed — three ablatives of means
mea culpa, mea máxima culpa—through my fault, through my most grievous fault — ablative; máxima is the superlative of magnus
ídeo precor—therefore I beseech — precor is also deponent
oráre pro me—to pray for me — pro + the ablative me
Prayer 6

Prayer 7
The Nicene Creed
Symbolum Nicaénum
This is the longer Creed professed at Sunday Mass. The Apostles’ Creed above is its shorter, older cousin, used in the Rosary and at Baptism; the Nicene Creed is the one you will actually recite standing at Mass, so it is worth learning even before the other.
Credo in unum Deum, Patrem omnipoténtem, factórem caeli et terrae, visibílium ómnium et invisibílium. Et in unum Dóminum Iesum Christum, Fílium Dei unigénitum. Et ex Patre natum ante ómnia saécula. Deum de Deo, lumen de lúmine, Deum verum de Deo vero. Génitum, non factum, consubstantiálem Patri: per quem ómnia facta sunt.
Qui propter nos hómines et propter nostram salútem descéndit de caelis. Et incarnátus est de Spíritu Sancto ex María Vírgine: et homo factus est. Crucifíxus étiam pro nobis: sub Póntio Piláto passus, et sepúltus est. Et resurréxit tértia die, secúndum Scriptúras. Et ascéndit in caelum: sedet ad déxteram Patris. Et íterum ventúrus est cum glória iudicáre vivos et mórtuos: cuius regni non erit finis.
Et in Spíritum Sanctum, Dóminum et vivificántem: qui ex Patre Filióque procédit. Qui cum Patre et Fílio simul adorátur et conglorificátur: qui locútus est per Prophétas. Et unam, sanctam, cathólicam et apostólicam Ecclésiam. Confíteor unum baptísma in remissiónem peccatórum. Et exspécto resurrectiónem mortuórum. Et vitam ventúri saéculi. Amen.
In EnglishI believe in one God, the Father almighty, maker of heaven and earth, of all things visible and invisible. And in one Lord Jesus Christ, the Only-Begotten Son of God, born of the Father before all ages. God from God, Light from Light, true God from true God, begotten, not made, consubstantial with the Father; through him all things were made. For us men and for our salvation he came down from heaven, and by the Holy Spirit was incarnate of the Virgin Mary, and became man. For our sake he was crucified under Pontius Pilate, he suffered and was buried, and rose again on the third day in accordance with the Scriptures. He ascended into heaven and is seated at the right hand of the Father. He will come again in glory to judge the living and the dead, and his kingdom will have no end. And in the Holy Spirit, the Lord, the giver of life, who proceeds from the Father and the Son, who with the Father and the Son is adored and glorified, who has spoken through the prophets. And in one, holy, catholic and apostolic Church. I confess one Baptism for the forgiveness of sins, and I look forward to the resurrection of the dead and the life of the world to come. Amen.

Sub Tuum Praesídium

Nostras deprecatiónes ne despícias in necessitátibus nostris, sed a perículis cunctis líbera nos semper, Virgo gloriósa et benedícta.

Si iniquitátes observáveris, Dómine, Dómine, quis sustinébit? Quia apud te propitiátio est, et propter legem tuam sustínui te, Dómine.
Sperávit ánima mea in Dómino. A custódia matutína usque ad noctem, speret Israël in Dómino. Quia apud Dóminum misericórdia, et copiósa apud eum redémptio. Et ipse rédimet Israël ex ómnibus iniquitátibus eius.
In EnglishOut of the depths I have cried to thee, O Lord. Lord, hear my voice. Let thine ears be attentive to the voice of my supplication. If thou, O Lord, wilt mark iniquities — Lord, who shall stand? For with thee there is forgiveness, and by reason of thy law I have waited for thee, O Lord. … For with the Lord there is mercy, and with him plentiful redemption. And he shall redeem Israel from all his iniquities.

Flashcards
Everything above, turned into cards. The decks are drawn from the tables and vocabulary lists of this primer itself, so nothing here is new to you — it is the same material, asking instead of telling.
Drill
Learn the Cards by Heart
Pick a deck. A card shows its Latin; call the meaning to mind, then turn it over. Got it retires the card, Again sends it to the back of the pile — a deck is not finished until every card has been answered rightly once. English first reverses the drill, which is harder and worth doing second.
Ten minutes a day will do more than an hour on Saturday. The decks you have cleared are marked, so you can begin again where you left off.
The flashcards need JavaScript. Without it, the tables in Parts I, II, IV and VI hold the same words — cover the right-hand column with your thumb and you have the same drill.
Part VIII
Next Steps
You now have a foundation. Six ways to build on it — none of them requiring a classroom.
Going further
Continuing Your Study
Attend the Traditional Latin Mass with a missal
There is no better classroom. Follow the text in a hand missal — the 1962 Roman Missal, or any traditional hand missal with facing-page translations. After a few weeks you will begin to anticipate the words before your eye reaches the English column.
Pray the Divine Office in Latin
Begin with Compline, the Church’s night prayer. It is brief and draws on the same few psalms daily, so the vocabulary repeats until it sticks. The Salve Regina closes Compline — and you already know it.
Memorize one new prayer a week
Start with Sub Tuum Praesídium, the Anima Christi, the opening of the Te Deum, and De Profúndis. Each one teaches new vocabulary organically, in the only context that makes words stay: prayer you mean.
Work through a grammar
A primer gets you to the door. A grammar takes you through it.
Wheelock’s LatinThe standard university grammar — secular, but rigorous.
Henle LatinA Jesuit grammar designed for Catholic students. Highly recommended.
Latin for CatholicsPrimers written specifically for the liturgy.
The Ordinary of the MassIn any hand missal — your primary textbook.
Divinum Officiumdivinumofficium.com — the Latin Divine Office, free and complete.
Vox Clara / Latin Mass MagazineCommentary on liturgical Latin.
Learn the Psalms
The Psalms are the backbone of Catholic prayer. Begin with Psalms 1, 23 (Dóminus regit me — “The Lord is my shepherd”), 51 (Miserére), 130 (De Profúndis), and 150 (Laudáte Dóminum). Remember that traditional Latin psalters number these from the Greek Septuagint, so Dóminus regit me is Psalm 22 in a Vulgate psalter and 23 in a modern Bible; likewise Miserére is 50 or 51, and De Profúndis 129 or 130. The Latin stands closer to Hebrew poetry than most modern translations, and vocabulary accumulates quickly.
Read the Vulgate
St Jerome’s Latin Bible — the Biblia Sacra Vulgáta of the fourth century — is the Church’s own Scripture text. Begin with the Gospel of St John, the Evangélium Secúndum Ioánnem: the vocabulary is simple and the theology is not. In princípio erat Verbum…
A closing note
Ecclesiastical Latin and the Soul
Learning Latin is not merely an intellectual exercise. When you pray Pater noster, qui es in caelis with understanding, you do not simply translate — you participate. The words were on the lips of St Thomas Aquinas, St Catherine of Siena, St Francis of Assisi, and countless anonymous souls who knelt before the same altar and addressed the same God in the same words.
Latin is continuity. It is the thread running through two thousand years of Catholic prayer, theology, and martyrdom. As Pope John XXIII wrote, it is “a most effective bond, binding the Church of today with that of the past and of the future in wonderful continuity.”
Every word you learn draws you further into that continuity — into the communio sanctórum, the communion of saints, who have praised God in these words before you, and will do so long after.
Deo grátias. ✠

This primer was prepared for Catholic learners desiring to pray, worship, and study in the language of the Church. It draws upon the Vulgate, the Roman Missal, papal documents, and the Church’s two-thousand-year tradition of sacred Latin.
