Pater consilium matris probat, quia pueris prodest.

The subject is pater because it is in the nominative case: pater = father.

The verb probat means approves or approves of. Its ending -t shows it is third person singular: he/she/it approves.

So:

• pater = the father
• probat = approves

That tells you the father is the one doing the approving.

Consilium is the direct object of probat, so it is in the accusative case.

It answers the question: What does the father approve?
Answer: consilium = the plan / advice / decision

A useful detail: consilium is a neuter noun of the second declension, and in many neuter nouns, the nominative singular and accusative singular look the same. So here consilium could be either nominative or accusative in form, but its job in the sentence shows it is accusative.

Because matris is genitive singular, meaning of the mother or the mother’s.

So:

• mater = mother (nominative, subject form)
• matris = of the mother / the mother’s (genitive)

In consilium matris, matris modifies consilium:

• consilium matris = the mother’s plan or the plan of the mother

English often uses 's, while Latin usually uses the genitive case instead.

Because prodest takes the dative for the person who benefits.

So:

• pueris = to the boys / for the boys
• prodest = is beneficial / is useful / helps

Together:

• pueris prodest = it benefits the boys or literally it is useful to the boys

This is very common in Latin: some verbs do not take a direct object in the accusative the way an English verb might. Prodesse is one of them.

Prodest is the third person singular present tense of prodesse, which means to benefit, to be useful, or to do good to.

It is a compound built from pro- + esse (to be), and it behaves somewhat irregularly because it comes from sum, esse.

Here:

• prodest = it benefits / it is beneficial

The subject of prodest is understood from context: in this sentence, the thing that benefits the boys is the mother’s plan.

So the second clause means:

• because it benefits the boys

Latin often leaves out a subject when it is already clear from context.

In quia pueris prodest, the subject is not stated explicitly, but we naturally understand it as consilium matris from the first clause.

So the full sense is:

• The father approves of the mother’s plan, because the mother’s plan benefits the boys.

Latin avoids repetition when the meaning is obvious.

Quia means because and introduces a causal clause—a clause giving the reason.

So:

• Pater consilium matris probat = the main statement
• quia pueris prodest = the reason why

This is a very straightforward factual because clause, so Latin uses the indicative verb prodest.

Latin word order is more flexible than English word order because Latin uses case endings to show each word’s job.

This sentence is arranged as:

• Pater = subject
• consilium matris = object + genitive modifier
• probat = verb
• quia pueris prodest = reason clause

A very natural English translation is:

• The father approves of the mother’s plan because it benefits the boys.

Latin often places the verb later in the clause, but the endings matter more than the position.

Because Latin has no articles.

There is no separate word for:

• the
• a
• an

So:

• pater can mean father, the father, or sometimes a father
• consilium can mean plan, the plan, or a plan

You choose the best English wording from the context. In this sentence, English most naturally uses the:

• the father
• the mother’s plan
• the boys

Not here. Although English prove and Latin probare are historically related, probare very often means to approve, to find good, or to accept.

So in this sentence:

• probat = approves of

A learner should be careful not to translate it automatically as proves.

The dictionary forms are:

• pater, patris — father
• consilium, consilii — plan, advice, decision
• mater, matris — mother
• probo, probare, probavi, probatum — approve, test, prove
• puer, pueri — boy
• prosum, prodesse, profui — benefit, be useful

Knowing the dictionary form helps you recognize why the actual forms look the way they do:

• matris comes from mater, matris
• pueris comes from puer, pueri
• prodest comes from prodesse

Yes. Consilium can mean several related ideas, depending on context, such as:

• plan
• advice
• decision
• strategy
• counsel

In this sentence, the exact English word depends on the meaning already given to the learner, but grammatically it works the same way: it is the thing the father approves of, and it is also the understood subject of prodest.
