Milites pugnam vitant.

Because milites is plural. It is the nominative plural form of miles, which means soldier.

• miles = soldier
• milites = soldiers

In this sentence, milites is the subject.

We know because milites is in the nominative plural, which is the case normally used for the subject of a sentence.

Also, the verb vitant ends in -nt, which shows a third-person plural subject: they avoid. That matches milites = the soldiers.

The -am ending shows that pugnam is accusative singular. The accusative case is commonly used for the direct object.

So here:

• milites = the soldiers → subject
• pugnam = the battle / fight → direct object

The soldiers are doing the action, and the battle is what they are avoiding.

The dictionary form is pugna, meaning battle or fight.

Here are the relevant forms:

• pugna = nominative singular
• pugnam = accusative singular

So in the sentence, Latin uses pugnam because it is the object of the verb.

Vitant is the third-person plural present active indicative of vito, vitare, meaning avoid.

Breaking it down:

• vit- = verb stem
• -a- = first-conjugation vowel
• -nt = they

So vitant means they avoid.

Latin normally does not use articles like the or a/an.

So:

• milites can mean soldiers or the soldiers
• pugnam can mean a battle, the battle, or just battle

The exact English translation depends on context.

Not exactly. English depends heavily on word order, but Latin depends much more on endings.

So Milites pugnam vitant means the same thing even if you rearrange it, for example:

• Pugnam milites vitant
• Vitant milites pugnam

The endings still show who is doing the action and what receives it.

That said, word order in Latin can still affect emphasis.

Yes. The Latin present tense can often be translated in more than one way in English, depending on context.

So vitant may mean:

• they avoid
• they are avoiding
• sometimes even they do avoid for emphasis

In a simple sentence like this, avoid is usually the most natural translation.

Because miles is a third-declension noun. Third-declension nouns often have forms that are less predictable than first- and second-declension nouns.

Its main forms are:

• miles = soldier
• militis = of the soldier
• milites = soldiers

So milites is the normal nominative plural form for this noun, even though it may look unfamiliar at first.

It is active.

That means the subject is doing the action:

• milites = the soldiers
• vitant = avoid
• pugnam = the battle

So the soldiers are actively avoiding the battle.

A passive sentence would look different and would mean something like the battle is being avoided, which is not what this Latin says.
