Triumvir monetalis monetam intrat.

Triumvir is the subject of the sentence, and it is nominative singular.

It does not end in -us because not all masculine Latin nouns are second-declension nouns. Triumvir belongs to the third declension, so its nominative singular has its own pattern.

The word literally means one of three men, and in Roman usage it often refers to a man holding a three-person office.

Monetalis is an adjective modifying triumvir.

Here it is:

• nominative
• singular
• masculine

because it agrees with triumvir.

Its basic sense is connected with the mint or money. In Roman official language, triumvir monetalis is a recognized title for a magistrate associated with coinage and the mint. In smoother English, this is often rendered as something like moneyer or mint magistrate.

Because monetam is the direct object of intrat.

Latin often uses the accusative after verbs that take a direct object, and intrare is one of those verbs. So monetam intrat means literally he enters the mint.

This may feel unusual to an English speaker, because English usually says enter plus a direct object too, but with some other motion verbs English prefers a preposition. Latin is simply treating the mint as the thing being entered.

Because intrare often takes a direct object in Latin.

So Latin commonly says:

• urbem intrat = he enters the city
• domum intrat = he enters the house
• monetam intrat = he enters the mint

English learners sometimes expect in monetam, but after intrare, Latin very often does not use a preposition.

Intrat is:

• present tense
• active voice
• indicative mood
• third person singular

from the verb intrare, meaning to enter.

So intrat means he enters, she enters, or it enters, depending on the subject. Here, since the subject is triumvir, it means he enters.

It can mean either, depending on context.

Latin present tense often covers both:

• simple present: enters
• progressive present: is entering

Without more context, either is grammatically possible.

Because Latin has no definite or indefinite article.

So a noun like triumvir can mean:

• a triumvir
• the triumvir

and monetam can mean:

• a mint
• the mint

The context tells you which is best in translation.

It is grammatically an adjective, but in this phrase it is also part of an official title.

So both ideas are true:

• grammatically: triumvir
  • monetalis = noun + agreeing adjective
• historically: triumvir monetalis refers to a specific Roman official connected with coinage

That is why the phrase can be translated either very literally or more idiomatically.

Yes, moneta can have meanings related to money, coinage, or the mint.

But in this sentence, because the verb is intrat (enters), the meaning mint is the most natural one. You can enter a building or place; that makes better sense than entering a coin.

So the grammar helps narrow the meaning.

Because Latin word order is more flexible than English word order.

Adjectives can come before or after the nouns they modify. In many cases, especially in formal or title-like expressions, the adjective after the noun is perfectly normal.

So triumvir monetalis is a natural Latin order.

Yes. The sentence has:

• subject: triumvir monetalis
• object: monetam
• verb: intrat

This is a very normal Latin pattern. Latin often places the verb at the end, although many other orders are also possible.

Because the endings show the grammatical roles, Latin does not rely on word order as heavily as English does.

We know from the case endings.

• triumvir is nominative singular, which is the usual case for the subject
• monetalis agrees with it, so it belongs with the subject
• monetam is accusative singular, which marks the direct object

So even if the word order changed, the endings would still show the roles clearly.

Yes, often it can.

For example, Latin could also say:

• Monetam triumvir monetalis intrat
• Triumvir monetalis intrat monetam

The basic meaning would stay the same because the cases still show who is doing the action and what is being entered.

However, different word orders can create different emphasis. The original order is straightforward and natural.
