Orichalcum conflatur.

It is nominative singular.

Even though orichalcum ends in -um, which can also be accusative singular for a second-declension neuter noun, here the verb is passive: conflatur = is melted / is smelted / is fused. In a passive sentence, the thing undergoing the action is the subject, so it must be in the nominative.

So orichalcum is the subject: the orichalcum / brass is being melted.

Because it is a neuter second-declension noun.

For second-declension neuter nouns, the nominative singular and accusative singular are both usually -um. So this is completely normal.

A learner may be used to second-declension masculine nouns like:

• servus = nominative singular
• servum = accusative singular

But neuter nouns work differently:

• bellum = nominative singular
• bellum = accusative singular

So orichalcum follows the neuter pattern, not the masculine one.

Conflatur is third person singular present passive indicative of conflare.

You can break it down like this:

• confla- = the present stem
• -tur = the ending for third person singular passive

So it means he/she/it is melted, and here the it is orichalcum.

The ending -tur is a very important passive ending in Latin. It means third person singular passive in the present system.

Compare:

• conflat = he/she/it melts or forges/fuses
• conflatur = he/she/it is melted or is forged/fused

So when you see -tur, a good first question is: Is this a passive verb? Very often, yes.

Yes, it is present tense.

Depending on context, a Latin present passive can be translated into English in more than one natural way:

• is melted
• is being melted
• is smelted
• is being smelted
• sometimes even a more general gets melted

The exact English wording depends on context. Latin present tense is often broader than a single English form.

The dictionary form is conflare.

Latin verbs are normally looked up under the first-person singular present active and principal parts, so you would expect something like:

• conflo, conflare, conflavi, conflatum

From that, conflatur is built as the present passive form.

Literally, conflare comes from con- plus flare, and flare means to blow.

So the original idea is something like to blow together or to blow upon, especially in a furnace or with metalworking. From that comes the sense to melt, fuse, smelt, cast, especially with metals.

So in a sentence like Orichalcum conflatur, the verb is very appropriate for metalworking.

Because the sentence is focused on the metal being worked, not on the person doing the work.

Latin often uses the passive when the important thing is the object undergoing the action:

• Orichalcum conflatur = The orichalcum is melted
• active equivalent: aliquis orichalcum conflat = someone melts the orichalcum

The passive lets Latin keep the spotlight on orichalcum.

If you want to add the agent, Latin often uses ab plus the ablative, especially for a personal agent.

For example:

• Orichalcum ab artifice conflatur.
• The orichalcum is melted by the craftsman.

If no agent is given, the sentence simply leaves that unspecified.

Yes. Latin word order is fairly flexible because the endings show the grammar.

So all of these could work, depending on emphasis:

• Orichalcum conflatur.
• Conflatur orichalcum.

The most neutral order here is probably the one you were given, but Latin does not depend on word order as strictly as English does.

You know from the verb form and the overall syntax.

Since conflatur is passive, it needs a subject: something is being melted. That subject is orichalcum.

If the verb were active, then orichalcum could be accusative instead:

• Aurifex orichalcum conflat.
• The craftsman melts the orichalcum.

There, orichalcum is the direct object. But in Orichalcum conflatur, it is the subject.

It is a real Latin word, borrowed from Greek, and it refers to orichalcum, often understood as a kind of brass or a valuable copper alloy.

A learner may notice that it looks a bit unfamiliar compared with very common classroom nouns. That is normal: it is a more specialized vocabulary item, especially connected with metals and materials.

In a common classroom pronunciation of classical Latin, roughly:

• orichalcum: o-ri-KHAL-kum
• conflatur: kon-FLA-tur

A few useful points:

• ch in classical Latin usually represents a hard k sound with aspiration, not English ch as in church
• c is always hard, like k
• u is pronounced like oo or a short u depending on length and setting, not like English yoo

So the whole sentence is approximately:

o-ri-KHAL-kum kon-FLA-tur

An active version would need someone performing the action, for example:

• Faber orichalcum conflat.
• The smith melts the orichalcum.

Now compare the grammar:

• Orichalcum conflatur. → passive; orichalcum is the subject
• Faber orichalcum conflat. → active; faber is the subject, orichalcum is the object

That contrast is a very useful way to understand the sentence.
