Bona fortuna mulierem iuvat, quia vicina clamorem audit et legem bene scit.

Because both words are in the nominative singular, which is the normal case for the subject.

• fortuna = nominative singular of fortuna
• bona = nominative singular feminine of bonus, agreeing with fortuna

So bona fortuna means good fortune and functions as the subject of iuvat.

Because mulierem is in the accusative singular, the case normally used for the direct object.

The verb iuvat means helps, so the person being helped is the direct object:

• mulier = woman (nominative singular)
• mulierem = woman (accusative singular)

So bona fortuna mulierem iuvat means good fortune helps the woman.

Iuvat is:

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

It comes from iuvo, iuvare, meaning to help.

So iuvat means he/she/it helps. Here the subject is bona fortuna, so it means good fortune helps.

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

• gender
• number
• case

Since fortuna is feminine singular nominative, bona must also be feminine singular nominative.

That is why Latin uses bona fortuna, not some other form like bonus fortuna or bonam fortuna.

Quia means because and introduces a subordinate clause giving a reason.

So the sentence is divided like this:

• main clause: Bona fortuna mulierem iuvat
• reason clause: quia vicina clamorem audit et legem bene scit

In other words: good fortune helps the woman because the neighbor hears the shout and knows the law well.

Here it is being used as a noun: neighbor.

Latin adjectives can often be used substantively, meaning they stand on their own as nouns when the noun is understood.

So vicina literally comes from an adjective meaning neighboring, but in this sentence it means the female neighbor or simply the neighbor.

It is nominative singular, so it is the subject of both audit and scit.

Because vicina is the subject of the verbs audit and scit.

The clause says:

• vicina ... audit = the neighbor hears
• vicina ... scit = the neighbor knows

Since the same subject does both actions, Latin states it once and uses nominative case for it.

Because clamorem is the direct object of audit.

• clamor = shout, cry, noise (nominative singular)
• clamorem = accusative singular

The verb audio, audire takes a direct object in the accusative when you hear something. So clamorem audit means she hears a shout or she hears the shouting.

Audit is:

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

It comes from audio, audire, meaning to hear.

So audit means he/she/it hears. Here the subject is vicina, so it means the neighbor hears.

Because legem is the direct object of scit.

• lex = law (nominative singular)
• legem = law (accusative singular)

The verb scio, scire means to know, and the thing known is put in the accusative. So legem scit means she knows the law.

Bene is an adverb meaning well.

It modifies the verb scit:

• legem bene scit = she knows the law well

It is not bona because bona is an adjective, and adjectives describe nouns. Here we need a word describing how she knows, so Latin uses the adverb bene.

Scit is:

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

It comes from scio, scire, meaning to know.

So scit means he/she/it knows. With vicina as the subject, it means the neighbor knows.

Classical Latin does not have articles like English the or a/an.

So a noun like mulierem can mean:

• a woman
• the woman

and vicina can mean:

• a neighbor
• the neighbor

Which one sounds best depends on context and translation choice.

Latin word order is much more flexible than English word order because the endings show each word’s role.

For example:

• bona fortuna is nominative, so it is the subject
• mulierem is accusative, so it is the object

That means Latin can put words in different positions without causing much confusion. English depends more heavily on word order, but Latin depends more on case endings.

This sentence is still fairly straightforward, but the order is not forced to be exactly English-style subject-verb-object.

The form vicina is feminine singular nominative.

It is the feminine form corresponding to masculine vicinus. So if the sentence had a male neighbor as the subject, we would expect vicinus instead.

Because the sentence uses vicina, the neighbor is grammatically feminine.

Because one subject, vicina, is doing two actions:

• audit
• scit

Latin does not need to repeat the subject before the second verb unless it wants special emphasis. So:

• vicina clamorem audit et legem bene scit

means:

• the neighbor hears the shout and knows the law well

This is completely normal Latin coordination.
