Rea felix est, quia iudex eam absolvit.

Rea is a noun meaning the accused woman, the female defendant, or the woman on trial. It is the feminine counterpart of reus.

In this sentence, rea is:

• nominative singular
• the subject of est

So rea felix est means that the defendant is the one who is happy.

Not all Latin adjectives use -us, -a, -um endings.

Felix is a third-declension adjective, and its nominative singular form is the same for masculine and feminine. So:

• masculine: felix
• feminine: felix

It still agrees with rea in gender, number, and case, even though the ending does not change the way a first/second-declension adjective would.

It can mean either, depending on context: happy, fortunate, lucky, or successful.

In this sentence, the meaning shown to the learner is probably something like happy or fortunate, and the clause with quia explains why. So the basic idea is that the defendant is in a good state because of what the judge did.

Quia means because. It introduces a clause giving the reason for the main statement.

So the sentence has two parts:

• Rea felix est = the main clause
• quia iudex eam absolvit = the reason clause

In other words, the second clause explains why the defendant is happy.

Because iudex is in the nominative singular, which is the normal case for the subject.

In the second clause:

• iudex = subject
• eam = direct object
• absolvit = verb

So the judge is the one doing the action, and her is the one receiving it.

Eam is the accusative singular feminine form of is, ea, id, and here it means her.

Latin often uses a pronoun instead of repeating the noun. So instead of saying iudex ream absolvit, the sentence says iudex eam absolvit.

If the noun had been repeated, it would have had to be ream, because the direct object must be in the accusative. The pronoun eam fills that same role.

In this isolated sentence, eam most naturally refers back to rea, because:

• eam is feminine singular
• rea is a feminine singular noun already mentioned
• the sense of the sentence strongly connects them

In a longer passage, eam could theoretically refer to another feminine singular person mentioned earlier. But in this sentence by itself, rea is the obvious referent.

Here it is understood as perfect, so the sense is acquitted or has acquitted.

A useful thing to know is that in ordinary Latin spelling, a form like absolvit can sometimes look the same whether it is present or perfect. So learners often have to use context to decide.

In this sentence, the intended meaning makes the perfect sense clear: the defendant is happy because the judge acquitted her.

Because the sentence describes:

• a present state: she is happy
• caused by an earlier completed action: the judge acquitted her

That is completely normal in Latin. English does the same thing very naturally:

• She is happy because the judge acquitted her.

So the acquittal happened first, and her happiness is the present result.

Latin usually does not need an expressed subject pronoun if the subject is already clear.

Here the subject is already stated as rea, so there is no need to add a separate word for she. Also, est already tells you the verb is third-person singular.

Latin often avoids unnecessary pronouns unless they are needed for emphasis or contrast.

No. Latin word order is much more flexible than English word order because the case endings show each word’s function.

This sentence is arranged in a very natural way:

• Rea first, introducing the person being talked about
• felix est, stating her condition
• quia ..., giving the reason

Other orders are possible, such as Iudex eam absolvit, quia rea felix est, but that would change the emphasis and might sound less natural for the intended meaning. The forms, not just the position, tell you who is doing what.
