Inter cenam familia de die longo loquitur.

Because inter is a preposition that takes the accusative case.

So:

• inter = during, among, between
• cenam is the accusative singular of cena = dinner

In this sentence, inter cenam means during dinner.

This is something worth memorizing: Latin prepositions regularly require a specific case, and inter always takes the accusative.

Latin often uses prepositional phrases where English might use a different structure.

Here:

• inter literally has the basic sense between/among
• but with expressions of time, it can mean during

So inter cenam is an idiomatic Latin way to say during dinner.

A learner should not try to translate each word too mechanically. The phrase as a whole means during dinner, even if inter does not always mean that in other contexts.

Because familia is a singular noun in Latin, just like family is singular in English.

So:

• familia = the family
• it refers to a group, but grammatically it is still singular

That is why the verb is also singular:

• familia ... loquitur = the family speaks / is talking

Latin treats familia as one grammatical unit here.

Because its subject is familia, and familia is grammatically singular.

So:

• familia = singular subject
• loquitur = he/she/it speaks or speaks/is talking in the 3rd person singular

Even though a family contains several people, Latin grammar matches the verb to the grammatical number of the noun, not necessarily to the number of people involved.

Loquitur is:

• present tense
• 3rd person singular
• from the verb loquor, loqui, locutus sum
• a deponent verb

That means it looks passive in form, but it has an active meaning.

So loquitur means:

• he speaks
• she speaks
• it speaks
• or in context, is talking

With familia as the subject, it means the family is talking.

A deponent verb is a verb that uses passive-looking forms but has an active meaning.

For loquor:

• loquor = I speak
• loqueris = you speak
• loquitur = he/she/it speaks

So the ending -tur normally looks passive to beginners, but with a deponent verb it is translated actively.

That is why loquitur does not mean is spoken here. It means speaks or is talking.

Because loquor is commonly used with de + ablative to mean talk about or speak about.

So:

• de = about, concerning
• die longo = the long day in the ablative

Together:

• de die longo loquitur = talks about the long day

This is a common Latin pattern:

• de
  • ablative after verbs of speaking, thinking, writing, and similar ideas

Because the preposition de takes the ablative case, not the accusative.

So:

• dictionary form: dies longus = a long day
• after de, it becomes de die longo = about the long day

Both words change because the adjective must agree with the noun:

• die = ablative singular of dies
• longo = ablative singular of longus

In Latin, adjectives agree with the nouns they describe in:

• gender
• number
• case

Here:

• die is ablative singular
• longo is also ablative singular
• both are masculine here, since dies is masculine in this sentence

So die longo means long day in the ablative after de.

This agreement is a basic feature of Latin grammar and very important to notice.

Familia is in the nominative singular.

Why?

Because it is the subject of the sentence, the thing doing the action:

• familia ... loquitur = the family talks

The nominative is the normal case for the subject of a Latin sentence.

Because Latin has no articles like English the or a/an.

So:

• familia can mean family, a family, or the family
• cenam can mean dinner or the dinner, depending on context
• die longo can mean a long day or the long day

The exact English translation depends on context, not on an article in the Latin.

Latin word order is more flexible than English word order because Latin shows grammatical relationships mostly through endings, not position.

So in this sentence:

• Inter cenam tells you the time setting
• familia is the subject
• de die longo gives the topic
• loquitur is the verb

English usually depends heavily on order, but Latin does not need to follow the same pattern. A Latin sentence can often rearrange its words for emphasis or style without changing the basic meaning.

Yes, often it could.

For example, these would still be understandable Latin:

• Familia inter cenam de die longo loquitur.
• De die longo familia inter cenam loquitur.
• Familia de die longo inter cenam loquitur.

The meaning would stay broadly the same because the endings show the roles of the words.

However, different word orders can create different emphasis. The original sentence begins with Inter cenam, which puts during dinner first and gives the sentence a setting right away.

It can mean either, depending on context.

The Latin present tense often covers both:

• simple present: speaks
• progressive present: is speaking / is talking

In this sentence, English usually prefers is talking because the scene is happening during dinner:

• During dinner, the family is talking about the long day.

But the family talks about the long day during dinner is also grammatically possible as a translation, depending on the context.

Here is the breakdown:

• inter = during, among, between
• cenam = accusative singular of cena, meaning dinner
• familia = family
• de = about, concerning, from/down from in other contexts
• die = ablative singular of dies, meaning day
• longo = ablative singular of longus, meaning long
• loquitur = speaks / is talking

A good habit for learners is to identify not just the meaning, but also the form and function of each word.
