Amici ex foro abeunt.

Here amici is nominative plural, so it means friends as the subject of the sentence.

A good clue is the verb abeunt, which is 3rd person plural: they go away / they depart. Since the verb is plural, amici naturally matches it as the plural subject.

It is true that amici can sometimes mean other things in other contexts, such as of the friend (genitive singular), but not here. In this sentence, the plural verb makes friends the correct reading.

Because ex takes the ablative case.

The noun forum is a 2nd-declension neuter noun:

• nominative singular: forum
• ablative singular: foro

So after ex, Latin requires foro, not forum.

That is why the phrase is ex foro = out of the forum / from the forum.

Here ex means out of or from.

It often suggests movement from inside something or from within a place. So ex foro gives the idea out of the forum or from the marketplace/forum area.

In simple terms:

• ex foro = from out of the forum

Abeunt is:

• present tense
• active voice
• indicative mood
• 3rd person plural

Its dictionary form is abeo, abire, abii (or abivi), abitum, meaning to go away, depart, or go off.

So abeunt means they are going away, they go away, or they depart.

Because Latin usually does not need an expressed subject pronoun.

The ending of the verb already tells you the subject:

• -unt = they

So abeunt already means they go away. Adding a separate pronoun such as ei or illi would usually only be done for emphasis or contrast.

That is why Amici ex foro abeunt is perfectly complete without a word for they.

Because abeo and eo are related but not identical.

• eo, ire = to go
• abeo, abire = to go away, go off, depart

The prefix ab- adds the sense of away. So:

• eunt = they go
• abeunt = they go away / depart

In this sentence, abeunt emphasizes departure, not just movement in general.

That is a very common question. The verb abeo is a compound of ab- + eo, but its forms do not simply collapse into abunt.

The present-tense forms are:

• abeo
• abis
• abit
• abimus
• abitis
• abeunt

So abeunt is the normal classical form. It keeps the e from eo.

Yes. Latin word order is much more flexible than English word order because the endings show the grammatical roles.

This sentence is a very natural order:

• Amici = subject
• ex foro = prepositional phrase
• abeunt = verb

Latin often places the verb near the end, so this sentence looks very normal.

Other orders are possible, for example:

• Ex foro amici abeunt
• Abeunt amici ex foro

These would mean basically the same thing, though the emphasis might shift slightly.

Because Latin has no definite or indefinite articles.

So Latin does not have separate words for:

• the
• a
• an

Whether you translate amici as friends or the friends, and foro as a forum or the forum, depends on the context.

That means:

• Amici can be friends or the friends
• ex foro can be from the forum or from a forum

By form alone, foro could be either dative singular or ablative singular, because those endings are the same for many 2nd-declension nouns.

But in this sentence it must be ablative, because ex requires the ablative.

So:

• form: foro
• case here: ablative singular
• reason: it follows ex

In Latin, forum originally refers to a public square, marketplace, or civic open area in a town.

So ex foro may be understood as:

• out of the forum
• from the marketplace
• from the public square

The best English translation depends on context, but grammatically it is the same Latin phrase.

Normally, no—not with this meaning.

To express movement away from a place, Latin usually uses a preposition such as ex, ab, or de with the ablative, depending on the nuance.

So for from the forum / out of the forum, ex foro is the expected expression.

Without ex, foro would not clearly mean from the forum here.
