Choragus siparium claudit.

In Latin, the endings usually tell you the job of each word.

• choragus is nominative singular, which is the form typically used for the subject
• siparium is accusative singular, which is the form typically used for the direct object
• claudit is the verb

So:

• choragus = the one doing the action
• siparium = the thing being closed

That is why choragus is the subject and siparium is the object.

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

So a Latin noun by itself can often be translated in different ways depending on context:

• choragus = the stage manager, a stage manager, or just stage manager
• siparium = the curtain, a curtain, or just curtain

In a simple teaching sentence like this, English usually adds the because it sounds more natural.

The ending -t tells you the verb is third person singular in the present tense.

So claudit means:

• he closes
• she closes
• it closes

Because the subject is choragus, a masculine noun referring to a person, English will normally use he closes.

Claudit is present tense.

That means the action is happening now, or is presented as a simple present fact:

• closes
• sometimes, depending on context, is closing

In basic Latin sentences, the simple present translation is usually best: closes.

Claudit comes from claudere, meaning to close or to shut.

It is a third-conjugation verb.

Its main forms are commonly given as:

• claudō = I close
• claudis = you close
• claudit = he/she/it closes

So in this sentence, claudit is the regular third-person singular present form of claudere.

Latin word order is much more flexible than English word order because the endings already show the grammatical roles.

A very common Latin pattern is:

subject + object + verb

So:

• Choragus siparium claudit

is a very normal Latin sentence structure.

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

• Siparium choragus claudit
• Claudit choragus siparium

All of these could still mean the same basic thing, because the endings help identify the parts.

Siparium is in the accusative singular.

The accusative case is commonly used for the direct object, meaning the person or thing directly affected by the action of the verb.

Here, the thing being closed is the curtain, so siparium is in the accusative.

This is a very common pattern in Latin:

• nominative subject
• accusative direct object
• verb

It behaves like a second-declension masculine noun in this sentence, so its nominative singular form ends in -us, which is very common.

However, choragus is originally a Greek loanword. Latin borrowed many words from Greek, especially in areas like theater, literature, and art.

For a learner, the important point here is simple:

• choragus is the subject
• it is a masculine singular noun
• its -us ending fits the nominative singular pattern you often see in second-declension masculine nouns

A siparium is a kind of theatrical curtain or stage curtain.

So this is a theater-related sentence:

• choragus = a stage manager / producer / chorus leader
• siparium = curtain
• claudit = closes

Knowing that both choragus and siparium are theater words helps the sentence feel more coherent.

Yes. Claudere can often be translated as either close or shut.

So depending on style, you could render the sentence as:

• The stage manager closes the curtain
• The stage manager shuts the curtain

Usually closes is the more neutral classroom translation, but shuts is not wrong.

No. Latin usually does not need a separate subject pronoun when the verb ending already tells you the person and number.

Because claudit already means he/she/it closes, Latin does not need a separate word for he.

So:

• Choragus claudit already clearly means The stage manager closes

Latin uses explicit pronouns mainly for emphasis, contrast, or clarity.
