Cum magistra dicat “taceatis,” discipuli intellegunt verbum in coniunctivo positum esse.

The main clause is discipuli intellegunt — the students understand.

The subordinate clause is cum magistra dicat — when/since the teacher says.

Then the sentence also contains:

• a direct quotation: taceatis
• an indirect statement after intellegunt: verbum in coniunctivo positum esse

So the sentence is built like this:

• Cum magistra dicat ... = background clause
• discipuli intellegunt ... = main statement
• verbum in coniunctivo positum esse = what the students understand

Here cum most naturally means when or since, depending on context.

With the subjunctive, cum often introduces a clause of:

• circumstance: when
• cause: since / because
• sometimes concession: although

So cum magistra dicat could mean:

• when the teacher says
• or since the teacher says

Without more context, either can be possible, but when is often the safest first translation.

Because cum is introducing a subordinate clause that takes the subjunctive.

So:

• cum ... dicat = when/since ... says
• not a simple standalone statement the teacher says

This is a very common Latin pattern: cum + subjunctive.

If you saw cum dicit, that would usually be a more purely temporal when he/she says with the indicative. But cum dicat gives the clause more of a circumstantial or causal feel.

Taceatis is:

• present
• active
• subjunctive
• second person plural

It comes from taceo, tacere = to be quiet / to be silent.

So literally it means something like:

• you all may be quiet
• you all should be quiet

In context, it functions as a command: be quiet!

Yes. It is a jussive subjunctive, which is one way Latin can give a command or exhortation.

So taceatis means:

• be quiet!
• you should be quiet
• let yourselves be quiet

Because it is second person plural, the teacher is speaking to more than one student.

A learner may compare it with the regular imperative:

• tacete = be quiet! (plural imperative)
• taceatis = a subjunctive command, often a little more formal, literary, or less blunt in tone

This is why the students understand that the word is in the subjunctive.

Because the teacher is addressing more than one person.

Latin -tis at the end here marks second person plural:

• you all
• you people

That matches discipuli later in the sentence, since the ones hearing the command are the students.

Because the students are noticing one specific word: taceatis.

So verbum means the word — singular — referring to that one quoted form.

If the sentence were talking about several quoted words, then verba would make sense.

This is an indirect statement after intellegunt.

Latin often uses:

• an accusative subject
• plus an infinitive

after verbs like:

• say
• think
• know
• understand
• perceive

So here:

• intellegunt = they understand
• verbum = the subject of the indirect statement, in the accusative
• positum esse = to have been placed
• in coniunctivo = in the subjunctive

So the whole thing means: they understand that the word has been placed in the subjunctive or more naturally: they understand that the word is in the subjunctive

Because verbum is a neuter second-declension noun.

For neuter nouns of this type:

• nominative singular = verbum
• accusative singular = verbum

So the form looks the same in both cases.

In this sentence, it is accusative because it is the subject of the indirect statement after intellegunt.

This is a very common point of confusion for English speakers: sometimes Latin case is not obvious from the ending alone, especially with neuter nouns.

Positum esse is the perfect passive infinitive of pono, ponere, posui, positum.

Literally it means:

• to have been placed
• to have been put

So verbum in coniunctivo positum esse literally means: that the word has been placed in the subjunctive

In smoother English, we would usually say:

• that the word is in the subjunctive
• that the word has been put in the subjunctive mood

Latin often uses expressions like this where English prefers a simpler phrasing.

Because it agrees with verbum.

Verbum is:

• neuter
• singular

So the participle describing it must also be:

• neuter
• singular

That gives positum.

Even inside an indirect statement, agreement still works normally:

• verbum ... positum esse

Coniunctivo is ablative singular.

It is used with in, so:

• in + ablative = in
• here, more idiomatically, in the subjunctive

This is grammatical terminology. Latin is saying that the word has been placed in the subjunctive mood.

You can think of in coniunctivo as shorthand for something like:

• in modo coniunctivo = in the subjunctive mood

Because the sentence is doing two different things.

After dicat, we get the teacher’s exact words:

• taceatis

That is direct speech.

After intellegunt, we get what the students understand:

• verbum in coniunctivo positum esse

That is not a quotation. It is reported content, so Latin uses an indirect statement.

So the sentence moves from:

• direct speech: what the teacher says to
• indirect statement: what the students understand about that speech

Yes. A straightforward plural imperative would be tacete.

So the teacher could have said:

• tacete = be quiet!

But the sentence specifically uses taceatis because the point is grammatical: the students recognize that the word is subjunctive.

So taceatis is chosen not just for meaning, but to illustrate the subjunctive form.

Yes, it is perfectly normal Latin word order.

The sentence is:

Cum magistra dicat taceatis, discipuli intellegunt verbum in coniunctivo positum esse.

Latin word order is flexible, but this arrangement is very natural:

• subordinate clause first: cum magistra dicat
• main clause next: discipuli intellegunt
• indirect statement last: verbum in coniunctivo positum esse

English speakers often want a fixed order, but in Latin the endings do most of the grammatical work, so word order can be used for clarity, rhythm, or emphasis rather than strict necessity.
