Mater natum suum vocat.

Because mater is in the nominative singular, the case typically used for the subject.

In this sentence:

• mater = the one doing the action
• vocat = calls
• natum suum = the person being called

So mater is the one who calls.

Because not all feminine Latin nouns belong to the first declension.

A beginner often learns that many feminine nouns end in -a, such as puella, but mater is different:

• mater is feminine
• but it belongs to the third declension

So its gender is feminine even though its ending is not -a.

Because natum is the direct object of vocat, so it must be in the accusative singular.

Compare:

• natus = nominative singular, used for the subject
• natum = accusative singular, used for the direct object

Since the mother is calling her son, son is the object of the action, so Latin uses natum.

Suum is also accusative singular masculine.

It matches natum because suum is describing natum. In Latin, adjectives must agree with the nouns they modify in:

• gender
• number
• case

So:

• natum = masculine, singular, accusative
• suum = masculine, singular, accusative

That is why you get natum suum.

Because possessive adjectives in Latin agree with the thing possessed, not with the possessor.

In English, we think mainly about the possessor: her son.
In Latin, the adjective must grammatically match son, not mother.

So even though the possessor is the mother, suum is:

• masculine because natum is masculine
• singular because natum is singular
• accusative because natum is accusative

Here suum means her own or simply her, referring back to the subject, mater.

This is an important point: suus, sua, suum usually refers back to the subject of the clause.

So in this sentence:

• mater = subject
• suum = belonging to that subject

That is why suum means her own here.

Because suum refers back to the subject of the sentence, while eius usually refers to someone else.

So:

• natum suum = her own son (the mother’s son)
• natum eius = his/her son belonging to another person, not the subject

That distinction is very common in Latin and is worth learning early.

Vocat is a verb form meaning:

• present tense
• third person singular
• from vocare = to call

So vocat means he/she/it calls or, depending on context, is calling.

Because the subject is mater, we understand it as she calls / the mother calls.

It can mean either, depending on context.

Latin present tense often covers both:

• calls
• is calling

English usually makes a stronger distinction between simple present and progressive, but Latin often does not.

So the sentence could be understood as either:

• Mother calls her son
• Mother is calling her son

depending on the situation.

Because Classical Latin has no articles.

Latin does not normally have separate words for the or a/an. Whether a noun should be understood as definite or indefinite depends on context.

So mater could mean:

• mother
• the mother

and natum suum could mean:

• her son
• her own son

The exact English wording depends on what sounds natural in translation.

Yes, it could be different.

Latin word order is more flexible than English because the endings show what each word is doing. So the sentence could also appear as:

• Mater suum natum vocat
• Natum suum mater vocat
• Suum natum mater vocat

All of these can mean the same basic thing.

The given order is perfectly normal. Putting suum after natum is also normal, since Latin adjectives do not have to come before the noun.

It can mean son, but learners should know that filius is the more common everyday word for son.

Natus literally means something like born one, and in context it can mean son. So the sentence is good Latin, but a beginner will also often meet:

• Mater filium suum vocat.

That means the same thing in a more straightforward way for many learners.

Yes. Latin often leaves out a subject noun or pronoun when the verb already shows the person and number.

For example:

• Vocat = he/she/it calls

So if the context already made it clear that the subject was the mother, Latin could omit mater.

However, in this sentence mater is included for clarity or emphasis.
