Cum pluit, sub porticu manemus.

In this sentence, cum introduces a time clause: when it rains.

Latin cum can have several meanings, such as:

• when
• since
• although

The exact meaning depends on the context and often on the verb form that follows it. Here, pluit is in the indicative, so cum is being used in a straightforward temporal sense: when.

So:

• Cum pluit = When it rains

Because pluit is an impersonal verb.

In English, we use a dummy subject: it rains.
But in Latin, no real subject is needed. The verb simply appears in the third person singular:

• pluit = it rains / it is raining

The it is not an actual thing in either language; English just requires a subject, while Latin does not.

Other weather expressions often work similarly in Latin.

Pluit is:

• present tense
• indicative mood
• active voice
• third person singular

It comes from pluo, pluere, meaning to rain.

So pluit literally means it rains or it is raining.

Because sub can take either the accusative or the ablative, depending on the meaning.

A useful rule is:

• sub + accusative = motion to a position under something
• sub + ablative = being/resting under something

Here the sentence means that we stay under the portico, not that we move there. So Latin uses the ablative:

• sub porticu = under the portico

If the idea were we run under the portico, you would expect sub porticum.

Porticu is ablative singular of porticus, porticūs.

A porticus is a portico, colonnade, or covered walkway.

This noun belongs to the fourth declension, which is why the ablative singular ends in -ū:

• nominative singular: porticus
• ablative singular: porticū

Many textbooks print the long vowel as ū, though it is often written simply as u: porticu.

Manemus comes from maneo, manēre, meaning:

• remain
• stay
• wait
• sometimes continue to be

The form manemus is:

• present tense
• first person plural
• active indicative

So it means we remain or we stay.

In this sentence, we stay sounds natural in English.

Because the ending of the verb already tells you the subject.

In manemus, the ending -mus means we. So Latin does not need to add nos unless it wants emphasis or contrast.

So:

• manemus = we stay
• nos manemus = we stay / we ourselves stay / we, as opposed to someone else, stay

Latin often leaves subject pronouns out because the verb ending is enough.

Not as much as in English.

Latin word order is relatively flexible because the endings show the grammatical relationships. So these would all mean roughly the same thing:

• Cum pluit, sub porticu manemus.
• Sub porticu manemus, cum pluit.
• Cum pluit, manemus sub porticu.

That said, word order can affect emphasis and style. The given order is very natural:

1. the time clause first: Cum pluit
2. then the main idea: sub porticu manemus

So it feels like: When it rains, we stay under the portico.

Yes. Cum clauses often use either the indicative or the subjunctive, depending on the meaning.

A simple distinction is:

• cum + indicative: ordinary time, when
• cum + subjunctive: often since, although, or a more descriptive/background when

In this sentence, pluit is indicative, so the clause is just a plain factual time clause.

A learner does not need to assume that every cum clause works exactly the same way; the verb form matters.

This is a very common Latin pattern. A phrase closely tied to the verb is often placed before it, especially for smooth, natural rhythm.

So:

• sub porticu manemus

puts the location right before the action: under the portico we stay.

Latin often places the verb at or near the end of the clause, though this is not a strict rule. Here manemus at the end sounds very natural.

A classroom pronunciation would be roughly:

• Cum = koom
• pluit = PLOO-it or sometimes more carefully PLU-it
• sub = soob
• porticu = POR-ti-koo
• manemus = mah-NAY-moos

So the whole sentence is approximately:

koom PLOO-it, soob POR-ti-koo mah-NAY-moos

If your course uses restored Classical pronunciation, the c in cum is always hard, like k, never like the c in city.

Yes. The Latin present tense can express either a specific present situation or a more general repeated one, depending on context.

So Cum pluit, sub porticu manemus can mean:

• When it rains, we stay under the portico
• Whenever it rains, we stay under the portico

If there is no additional context, both are possible. The broader situation usually tells you whether it is a single event or a habitual action.
