Postquam ratis ad alteram ripam pervenit, mater dicit melius fuisse portitore prudente uti quam per vadum ire.

Postquam means after and introduces a time clause.

In this sentence:

• Postquam ratis ad alteram ripam pervenit
  = After the raft reached the other bank

A common thing for English speakers to notice is that Latin often uses a perfect tense after postquam where English might naturally use had reached or simply reached, depending on context.

So pervenit is perfect:

• literally: reached
• in smoother English: after the raft had reached the other bank

Latin is comfortable using the perfect here without needing a separate pluperfect.

Ratis means raft.

Here it is nominative singular, because it is the subject of pervenit:

• ratis ... pervenit = the raft arrived/reached

A learner might wonder whether ratis could be some other case, because many 3rd-declension nouns have forms that look less familiar than 1st- and 2nd-declension nouns. But here the verb makes it clear: the raft is the thing doing the arriving, so ratis is nominative.

Ad takes the accusative case, so ripam is accusative singular.

• ad ripam = to the bank
• ad alteram ripam = to the other bank

Alteram means the other (of two). That makes good sense here, because a river naturally has two banks, and the sentence means the raft got to the bank on the opposite side.

So:

• ad = to, toward
• alteram = the other
• ripam = bank/shore

Pervenit comes from pervenire, meaning to arrive, to reach, or to come to.

With ad + accusative, it means reached or arrived at:

• ad alteram ripam pervenit = reached the other bank

So although pervenire can sometimes be translated as arrive, in this sentence reached is probably the most natural translation.

Because dicit refers to the mother’s act of speaking, not to the crossing itself.

The timeline is:

1. the raft reaches the other bank
2. then the mother says something about what would have been better

So:

• pervenit = the raft reached
• dicit = the mother says / is saying

Latin often uses the present in narration to make the scene vivid, or simply because the speaker is presenting the mother’s statement as current within the story.

This is one of the most important grammar points in the sentence.

After verbs like dicit (says), Latin often uses an indirect statement construction. Here the statement is essentially:

• melius fuisse ... = that it had been better ...

Why fuisse?

• fuisse is the perfect infinitive of esse
• it shows that the being better is earlier than the mother’s present act of speaking

So the mother is saying, after the event, that it would have been better to do something else.

In other words:

• dicit = she says
• melius fuisse = that it was / had been better

English often translates this more naturally as:

• Mother says it would have been better...

Melius is the neuter comparative form of bonus, and it is often used impersonally to mean better.

So:

• melius est = it is better
• melius fuisse = it was / had been better

Latin frequently uses the neuter singular comparative in this impersonal way.

Why not melior?

• melior is masculine/feminine singular: better describing a person or thing
• melius is neuter singular, and here it functions as better in the sense of it is better

So the construction is not describing a noun like a better boatman. It is making a general judgment:

• it was better to use a prudent boatman than to go through the ford

Because this is an impersonal idea.

In many indirect statements, Latin uses:

• an accusative subject
• plus an infinitive

For example:

• dicit puerum venire = he says that the boy is coming

But here the statement is not about some person or thing doing the main infinitive fuisse. Instead, it is an impersonal judgment:

• melius fuisse = that it had been better

There is no need for an accusative subject like id or hoc, because Latin can leave the idea impersonal.

Because utor, uti, usus sum (to use) takes the ablative case.

That is a classic Latin feature that English speakers have to learn: some verbs govern cases that do not match English expectations.

So:

• uti portitore = to use a boatman/ferryman
• portitore prudente = to use a prudent boatman

Both words are ablative singular:

• portitore = boatman / ferryman
• prudente = prudent, careful

The adjective agrees with the noun in case, number, and gender.

It looks passive, but it is actually deponent.

Utor, uti, usus sum is a deponent verb:

• it has passive-looking forms
• but active meaning

So uti means:

• to use

not:

• to be used

That is why portitore prudente uti means:

• to use a prudent boatman or more naturally,
• to make use of a prudent boatman/ferryman

Quam means than and introduces the second half of a comparison.

The comparison is:

• melius fuisse portitore prudente uti quam per vadum ire

= that it had been better to use a prudent boatman than to go through the ford

So the two things being compared are:

1. portitore prudente uti = to use a prudent boatman
2. per vadum ire = to go through the ford

Ire means to go.

Per vadum means through the ford or across at the ford.

A vadum is a ford, a shallow place where one can cross water on foot or otherwise without a boat.

So:

• per vadum ire = to go through the ford / to cross by way of the ford

This contrasts neatly with traveling by raft or with a ferryman.

They refer to very different things connected with a river.

• ripa = bank, shore
• vadum = ford, a shallow crossing-place

So in the sentence:

• the raft reaches the other bank
• the mother says it would have been better to use a prudent boatman than to go through the ford

A learner may confuse them because both are river vocabulary, but one is a place beside the river, while the other is a place to cross the river.

Latin word order is much more flexible than English word order because Latin uses case endings to show grammatical relationships.

So the sentence can place words for emphasis or style rather than strict subject-verb-object order.

For example:

• Postquam ratis ad alteram ripam pervenit
  puts the time clause first.
• mater dicit
  introduces the mother’s statement.
• melius fuisse ... quam ...
  places the judgment better before the two infinitive phrases being compared.

English speakers often want to rearrange everything into a more familiar order. That is normal and often helpful when first analyzing the sentence.

A more English-like order would be something like:

• After the raft reached the other bank, mother says that it had been better to use a prudent boatman than to go through the ford.

Yes. Portitor can be translated in different ways depending on context, including:

• boatman
• ferryman
• carrier

In this sentence, ferryman is probably especially natural, because the context is river crossing.

So:

• portitore prudente uti could be understood as
  to use a careful ferryman
  or
  to rely on a prudent boatman

A good way is to build it in pieces:

1. Postquam ratis ad alteram ripam pervenit
   = After the raft reached the other bank

2. mater dicit
   = mother says

3. melius fuisse
   = that it had been better / that it would have been better

4. portitore prudente uti
   = to use a prudent ferryman

5. quam per vadum ire
   = than to go through the ford

Put together:

• After the raft reached the other bank, mother says that it would have been better to use a prudent ferryman than to go through the ford.

That kind of step-by-step assembly is often the easiest way to read a Latin sentence confidently.
