Missio gladiatori victo datur.

The main verb is datur.

It comes from do, dare, dedi, datum, meaning to give.
Here it means is given.

So the sentence is built around the idea of something being given.

Datur is:

• 3rd person singular
• present tense
• passive voice
• indicative mood

So grammatically it means is given.

The -tur ending is a very common sign of the 3rd person singular passive in Latin.

Because missio is in the nominative singular, which is the case normally used for the subject of a finite verb.

In an active sentence with do, the thing being given would usually be the direct object. But in a passive sentence, that direct object becomes the subject.

So the active idea would be something like:

• Someone gives missio to the defeated gladiator

and the passive sentence becomes:

• Missio is given to the defeated gladiator

That is why missio is the subject here.

Gladiatori is in the dative singular because it is the person to whom something is given.

With do, Latin regularly uses:

• accusative for the thing given in an active sentence
• dative for the recipient

In the passive, the thing given becomes the nominative subject, but the recipient usually stays in the dative.

So:

• gladiatori = to the gladiator

And victo is also dative because it agrees with gladiatori.

Together they mean:

• to the defeated gladiator

Victo is the perfect passive participle of vinco, vincere, vici, victum, meaning to defeat or to conquer.

The participle is victus, victa, victum = defeated.

Here, victo is:

• masculine
• singular
• dative

It is being used adjectivally to describe gladiatori.

So gladiatori victo means to the defeated gladiator.

We know because of agreement.

Latin adjectives and participles agree with the nouns they modify in:

• gender
• number
• case

Here:

• gladiatori = masculine singular dative
• victo = masculine singular dative

So victo is modifying gladiatori.

This is a very common Latin pattern: a noun plus a participle or adjective agreeing with it.

By form alone, victo could be dative singular or ablative singular. That ending can represent either case.

But in this sentence, dative makes sense because:

• it agrees with gladiatori
• gladiatori is naturally the recipient after datur
• gladiatori victo forms one clear phrase

So although the form itself is ambiguous, the syntax makes the meaning clear.

Latin often uses the passive when the speaker wants to emphasize the action as something that happens to the subject, rather than focusing on the person doing it.

Here the focus is on missio being granted.

An active version would be something like:

• Aliquis missionem gladiatori victo dat
• Someone gives mercy/release to the defeated gladiator

But the passive version is more impersonal and keeps attention on the granting itself:

• Missio gladiatori victo datur

This kind of passive is very natural in Latin.

Latin word order is much more flexible than English word order because the case endings show the grammatical relationships.

Putting the verb at the end is extremely common in Latin, especially in straightforward prose.

So this order:

• Missio gladiatori victo datur

is perfectly normal.

Latin could also rearrange the words for emphasis, for example:

• Gladiatori victo missio datur

The basic meaning would stay the same because the endings still show each word’s role.

Classical Latin does not have definite and indefinite articles like English the and a/an.

So a noun like missio can mean, depending on context:

• a release
• the release
• simply release

Likewise gladiatori victo could be understood as:

• to a defeated gladiator
• to the defeated gladiator

The context tells you which is most natural.

Yes, it is related historically, because both come from the Latin verb mitto, meaning to send.

But in this sentence, missio does not mean mission in the modern English sense.

Its basic Latin sense is something like:

• a sending away
• dismissal
• release

In gladiatorial context, missio is the technical term for the defeated gladiator being spared or released rather than killed.

So it is etymologically related to English mission, but the meaning here is quite different.

Because Latin passive sentences often leave the agent unstated when it is unknown, obvious, or unimportant.

The sentence simply says that missio is given. It does not say by whom.

If Latin wanted to express the agent, it could use ab or a with the ablative, for example:

• Missio gladiatori victo ab imperatore datur
• Missio is given to the defeated gladiator by the emperor

But in your sentence, the giver is left unspecified.

Yes. For an English-speaking learner, that is a very helpful way to think about it.

In an active version:

• someone gives release to the defeated gladiator

the defeated gladiator is the indirect object in English, and Latin usually expresses that role with the dative case.

So gladiatori victo is functioning like an indirect object: the recipient of what is given.
