Magistra rogat cur hoc verbum in coniunctivo, non in indicativo, positum sit.

Because cur hoc verbum in coniunctivo, non in indicativo, positum sit is an indirect question depending on rogat.

A direct question would be:

Cur hoc verbum in coniunctivo, non in indicativo, positum est?
= Why has this word been placed in the subjunctive, not in the indicative?

When Latin reports that question after a verb like rogat (asks), it normally changes the verb of the question into the subjunctive:

• direct: positum est
• indirect: positum sit

So the subjunctive here does not mean doubt or unreality; it is simply the normal grammar of an indirect question.

There are three main clues:

1. rogat = asks
2. cur = why
3. the verb in the dependent clause is in the subjunctive: sit

So the structure is:

• Magistra rogat = The teacher asks
• cur ... positum sit = why ... it has been placed

That is the standard pattern for an indirect question in Latin: a verb of asking, knowing, seeing, telling, etc. + a question word such as cur, quid, ubi, num, utrum + a subjunctive verb.

Because Latin uses different constructions for reported statements and reported questions.

A reported statement usually uses the accusative + infinitive:

• Magistra dicit hoc verbum in coniunctivo positum esse.
• The teacher says that this word has been placed in the subjunctive.

But a reported question uses an indirect question with the subjunctive:

• Magistra rogat cur hoc verbum in coniunctivo positum sit.
• The teacher asks why this word has been placed in the subjunctive.

So positum esse would fit a statement, not a question introduced by cur.

Positum sit is the perfect passive subjunctive, third person singular, of pono, ponere, posui, positum (to place, put).

It is made up of:

• positum = perfect passive participle
• sit = present subjunctive of sum

Together they mean has been placed or was placed, depending on context.

Because the subject is hoc verbum, which is neuter singular, the participle is also neuter singular: positum.

The perfect is used because the placing of the word is viewed as already done at the time the teacher asks about it.

In other words, the teacher is asking why the word has been put in the subjunctive.

So:

• positum sit = has been placed / was placed
• a present subjunctive such as ponatur would suggest something more like is being placed or is placed in a more immediate or general sense

Since the main verb rogat is present, Latin is using primary sequence, and for action prior to the main verb it commonly uses the perfect subjunctive in the indirect question.

Because verbum is a neuter noun.

The demonstrative hic, haec, hoc must agree with the noun it modifies in gender, number, and case. Since verbum is neuter singular, the correct form is:

• hoc verbum = this word

Not:

• hunc verbum — incorrect, because hunc is masculine accusative singular

Also, in neuter nouns, the nominative and accusative singular are the same, so hoc verbum can serve as the subject here.

Because it agrees with verbum.

In the passive perfect system, the participle must agree with the subject in:

• gender
• number
• case

Here the subject is hoc verbum:

• verbum = neuter singular nominative

So the participle must be:

• positum = neuter singular nominative

If the subject were feminine singular, you would expect posita; if masculine singular, positus.

They are ablative because they follow in in the sense of in or within a category/state, not motion into something.

So:

• in coniunctivo = in the subjunctive
• in indicativo = in the indicative

This is the normal construction with in + ablative for position or state.

The phrase positum in coniunctivo literally means something like placed in the subjunctive. In English we might often say more naturally put in the subjunctive or simply in the subjunctive.

No. Cur means why, but it does not by itself require the subjunctive.

In a direct question, Latin would often use the indicative:

• Cur hoc verbum positum est?
• Why was this word placed?

In this sentence, the subjunctive appears because the whole clause is indirect, not because cur alone demands it.

So the real rule is:

• direct question: often indicative
• indirect question: subjunctive

The core structure is:

• Magistra rogat = The teacher asks
• cur hoc verbum ... positum sit = why this word ... has been placed

Latin word order is flexible, but this arrangement is very natural. The phrase

in coniunctivo, non in indicativo

is placed before positum sit to highlight the contrast between the two moods.

A very literal order would be:

The teacher asks why this word, in the subjunctive, not in the indicative, has been placed.

In smoother English, we would usually say:

The teacher asks why this word has been placed in the subjunctive, not in the indicative.

Literally, positum sit is has been placed or was placed.

But in English, especially in grammatical discussion, a more natural translation may be:

• why this word is in the subjunctive, not in the indicative

So there are two levels:

• literal Latin grammar: has been placed
• natural English idiom: is

Both can be right, depending on how closely you want to mirror the Latin wording.
