Magister in tabula exemplum bonum scribit, et discipuli id in charta scribunt.

They match different subjects.

• scribit = he/she writes
• scribunt = they write

So:

• magister is singular, so Latin uses scribit
• discipuli is plural, so Latin uses scribunt

This is one of the most important things to notice in Latin: the verb ending tells you who is doing the action.

Both are in the nominative case, because they are the subjects of their clauses.

• magister = the teacher, the one who writes
• discipuli = the students, the ones who write

In Latin, the nominative is the case normally used for the subject of a verb.

Exemplum bonum is in the accusative case, because it is the direct object of scribit.

It answers the question what does the teacher write?
Answer: a good example

A very common pattern in Latin is:

• subject in the nominative
• direct object in the accusative
• verb agreeing with the subject

Because bonum has to agree with exemplum.

Exemplum is:

• neuter
• singular
• accusative

So the adjective describing it must also be:

• neuter
• singular
• accusative

That gives bonum.

If the noun were masculine singular nominative, you might see bonus. But here the noun is exemplum, so bonum is the correct form.

Id is the neuter singular accusative form of the pronoun is, ea, id.

It is used because it refers back to exemplum, which is:

• neuter
• singular

Since id is the object of scribunt, it must also be in the accusative.

So id means it here, specifically referring back to exemplum.

There are two main clues:

1. Meaning/context: the students are writing the same thing the teacher wrote.
2. Grammar: id is neuter singular, and exemplum is also neuter singular.

That agreement helps the reader connect the pronoun with its antecedent.

Here in shows location, so it takes the ablative case.

So:

• in tabula = on/in the board
• in charta = on/in the paper

More exactly, with macrons, these would be:

• in tabulā
• in chartā

In many printed texts, macrons are omitted, so tabula and charta look the same as nominative forms. But after in meaning location, they are understood as ablative.

Because Latin in with the ablative can cover meanings that English splits into in and on, depending on the noun and the situation.

So:

• in tabula is often understood as on the board
• in charta is often understood as on paper

English chooses the more natural preposition, but the Latin structure is still in + ablative for location.

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

So:

• magister can mean the teacher or a teacher
• exemplum bonum can mean a good example or the good example
• discipuli can mean the students or students

The correct choice in English depends on the context.

Latin word order is more flexible than English word order, because the endings show each word’s job.

So this sentence could be rearranged in other ways and still mean basically the same thing, as long as the forms stay the same.

The given order is quite natural:

• Magister first, as the subject
• in tabula early, giving the setting
• exemplum bonum before the verb
• scribit at the end of the clause, which is very common in Latin

Then the second clause mirrors the first:

• discipuli
• id
• in charta
• scribunt

That parallel structure makes the sentence easy to follow.

They refer to different writing surfaces.

• tabula can mean a board, tablet, or writing surface
• charta means paper or a sheet of paper

So the sentence contrasts where the teacher writes and where the students write:

• the teacher writes on the board
• the students write it on paper

That contrast helps explain why the sentence uses both nouns.

Latin sometimes does leave out words that are understood from context, but here id is useful because it clearly shows what the students are writing.

Without id, the sentence would still be understandable in some contexts, but including it makes the connection explicit:

• the teacher writes a good example
• the students write it

So id adds clarity and neatly links the two clauses.
