Latin Tattoo Phrases: Grammatical Ones and Famous Mistakes

By Michael McGettrickUpdated 12 October 2026

The famous phrases are fine. Horace, Vergil, Caesar and the Vulgate do not make mistakes. The errors come from customising: an adjective that does not match the wearer, a noun dropped into carpe without its accusative, a phrase nobody ever wrote in Latin. Here are 36 phrases checked, then the errors that actually get inked.

Quick check

Now use it: three quick questions on the chart above. The full practice is further down.

Spot the mistake

0/3

Each was meant as an order with an object, or a phrase after per. Tap the wrong ending.

How much a phrase depends on who wears it is a gradient:

Safe on anyoneCheck against the wearer
  1. dum spiro speroverbs only
  2. semper fortisone form for both
  3. invictus maneo-us: a man

Orders: carpe diem and memento mori

accusativethe verb endingWhat do the colours mean?

An imperative gives an order to the person reading it, and its object goes in the accusative. Nothing in these describes the wearer, so they suit anyone.

SourcePhraseLiterally
Horace, Odes 1.11carpe pluck the day
a later motto remember to die
Augustus, in Greekfestina lentehurry slowly
a proverb live so that you may live
D'Annunzio remember always to dare
Vegetius, adapted if you want peace, prepare war
Delphic maxim know yourself
Matthew 5:16luceat let your light shine

is literally remember to die; the sense is remember that you will die. is the imperative of , and is the infinitive of the .

Luceat is the odd one out: luceat is a jussive subjunctive, an order to a third party, let it shine. Carpe means pluck, as you pluck ripe fruit, which is gentler than seize.

The Matrix's temet is also correct: temet is with the emphatic -met, know your own self. Cicero quotes the maxim as plain .

I breathe, I hope: first-person verbs

the verb endingWhat do the colours mean?

A Latin verb ending carries the person (I, you, he/she), never the gender. These are the safest tattoos there are.

SourcePhraseLiterally
South Carolina spiro sperowhile I breathe, I hope
Caesar, in Suetonius I came, I saw, I conquered
São I am not led, I lead
Descartescogito I think, therefore I am
Horace, Odes 3.30 I shall not wholly die
attrib. Hannibal I shall find a way or make one

The ending is the thing to check. One letter changes who is speaking:

  • spero - I hope.
  • sperat - he/she hopes.

does contain an adjective describing the speaker, , whole. It is third declension, one form for men and women, so it is right on anyone.

Sayings about the world

genitiveablativethe verb endingWhat do the colours mean?

Proverbs and mottoes with their own subject talk about the world, not the wearer, so they suit anyone too.

With a verb

SourcePhraseLiterally
Vergil, Ecl. 10.69 love conquers all
Vergil, Aen. 10.284 iuvatfortune helps the daring
Terence, Phormio 203 adiuvatfortune helps the brave
after Vergil time flees
after Suetonius, Jul. 32alea iacta the die has been cast
fluctuat mergituris tossed but not sunk
Scotland impune lacessitno one provokes me unpunished
a proverb he conquers who conquers himself
Oregonalis volat flies with its own wings
papal coronation thus passes the glory of the world
Eusebius, in Latin in this sign you will conquer
a proverb , while there is life, there is hope

in Terence's line is an accusative plural (the usual spelling is ): the brave. Read as a nominative it would make fortune brave, which is not what he meant.

Vergil wrote , the older spelling of , and inreparabile , from which is cut. Suetonius has the words in the order iacta alea . Volat is he, she or it flies; Oregon translates its motto as she flies with her own wings.

No verb needed

SourcePhraseLiterally
Nietzsche love of fate
after Hippocrates , art is long, life is short
a motto deeds, not words
Sallust, Cat. 54.6 to be rather than to seem
a motto astrathrough hardships to the stars
a motto towards better things
Francis Drake great things from small

Latin leaves out freely: is art (is) long. In astra both nouns are accusative neuter plurals, because per and ad both take the accusative.

Phrases that describe you

masculinefeminineWhat do the colours mean?

If an adjective or noun describes the wearer, it agrees with the wearer, including in gender. This is where customised tattoo Latin most often goes wrong.

I remain unconquered: said by a man, then by a woman
MeaningA manA woman
unconqueredinvictusinvicta
blessed
alone
loved
winnervictrix
commanderimperatrix

Invictus , the motto of the Armstrongs, is right for a man; a woman needs invicta . The last two rows are nouns, but the rule is the same: a woman is a victrix.

Most third-declension adjectives have one form for men and women, so they cannot go wrong (a few, such as acer, acris, keen, have two):

AdjectiveMeaningExample
brave
faithful
lucky
audaxboldaudax
whole

, always faithful, is the motto of the US Marine Corps, and it fits every Marine.

Carpe noctem, not carpe nox

accusativeWhat do the colours mean?

Carpe is an order and its object goes in the accusative. A dictionary gives you the nominative, so a noun swapped into carpe X has to change its ending.

the dictionary form, then the accusative carpe needs
You wantLatinNot
the daycarpe carpe
the nightcarpe carpe
lifecarpe carpe
the bookcarpe carpe

Carpe is not nonsense, which is the trouble: it says pluck, O life, or read with a long final a, pluck with life. Neither is seize life.

Carpe is grammatical, and can mean a moment, but its first senses are a movement and a deciding weight, so a Latin reader may also see pluck the impulse.

Not Latin at all

  • illegitimi carborundum, don't let the bastards grind you down: mock Latin, a joke usually traced to the British Army in the Second World War. Carborundum is a trade name for an abrasive.
  • , always where under where: an English pun on always wear underwear.
  • Dio può giudicarmi, only God can judge me, is Italian. The Latin is iudicare .

The machine-translation deserves a word. Tools hand back the dictionary form where the sentence needs an accusative, and an -us adjective whoever the wearer is. Translate the result back into English and you will often get a different sentence.

Check a phrase before the needle

  1. Find the verb. Check the person: spero is I hope, sperat he/she hopes.
  2. Check every object and preposition. After carpe, and , the accusative: astra. After , , and , the ablative: .
  3. Check any word that describes you. -us for a man, - for a woman, or a third-declension adjective for either.
  4. Trace it to a source. Real phrases have an author or a dated motto. If it appears only in tattoo galleries, that is an echo, not attestation.

Classical inscriptions used capitals with V for U: IVLIVS for Julius. If you want that look, commit to it everywhere.

What to do next

  1. Learn adjective agreement, the twenty minutes that any tattoo.
  2. Read the Latin case system for the accusative.
  3. Then Latin phrases used in English and legal Latin.

Frequently asked questions

What is the best short Latin phrase for a tattoo?
If you want something short that cannot go wrong on gender, the strongest options are spiro spero (while I breathe, I hope), (deeds, not words), (remember to die: remember you will die) and astra (through hardships to the stars). All four are grammatical and long established, though they are later mottoes rather than classical quotations. None contains an adjective describing the wearer, which is where most tattoos come unstuck. is also safe for anyone, because has one form for men and women.
Are Latin tattoo phrases usually grammatically wrong?
The famous ones are usually fine, because they come from real Latin authors: Horace, Vergil, Caesar, Cicero and the Vulgate. The wrong ones are almost always personalised: someone swaps a word into a correct phrase, or runs an English sentence through a translation tool that has no idea which case the verb needs. The other big source of is gender, because an adjective describing you has to agree with you. The risk is not in the Latin; it is in the customisation.
Do Latin tattoo phrases change if you are a woman?
Sometimes, and it depends on the adjective. Adjectives like , change: invictus becomes invicta, becomes , becomes . Third-declension adjectives do not: , , audax and have one form for men and women. Verb endings never change for gender, so spiro spero and are identical whoever wears them (only a participle, as in , I have been conquered, does). If your phrase describes you and has a word ending in -us, check it before you book.
Is temet real Latin, or did The Matrix make it up?
It is real Latin, but not the classical phrasing. Cicero quotes the Delphic maxim as plain , know yourself, and is the fuller later form. Temet is with the emphatic suffix -met, so temet parses correctly: know your own self. The Oracle's door in the film is why most people have heard it. Both work; is the one with the pedigree.
What does mean literally?
Remember to die. is the imperative of , I remember, and is the infinitive of the , to die. The sense the phrase has carried for centuries is remember that you will die. It is a medieval and later motto rather than a classical quotation, and it is grammatical on anyone, because nothing in it describes the wearer.
