Bonus iudex iustitiam potius quam iram spectare debet.

Iudex is nominative singular, and it is the subject of debet.

So the core structure is:

• iudex ... debet = the judge ought / must

The adjective bonus goes with iudex, so together they mean a good judge or the good judge, depending on context.

Because bonus has to agree with iudex in case, number, and gender.

Here:

• iudex = nominative singular
• bonus = nominative singular masculine

So bonus iudex means a good judge as the subject.

A useful point for learners: iudex is a third-declension noun, but the adjective bonus is a first/second-declension adjective. They do not have to look alike; they just have to match in grammatical features.

Both iustitiam and iram are accusative singular.

They are accusative because they are the things the judge ought to spectare—that is, the direct objects of the infinitive spectare.

So:

• iustitiam spectare = to look to / regard justice
• iram spectare = to look to / regard anger

This is also why both words end in -am: they are both first-declension accusative singular forms.

Because after debet, Latin normally uses an infinitive.

So:

• debet = ought / must
• spectare = to look at / to regard

Together, spectare debet means ought to regard or must consider.

If you had spectat, that would mean he/she looks at, which would make a different sentence.

Literally, spectare often means to look at, observe, or watch. But in a sentence like this, it has a more extended sense: to look to, have regard for, consider, or pay attention to.

So the point is not that a judge literally stares at justice instead of anger. It means a judge should be guided by justice, not by anger.

That kind of broader meaning is very common in Latin.

Potius quam means rather than.

In this sentence it sets up a comparison between two things:

• iustitiam
• iram

So:

• iustitiam potius quam iram = justice rather than anger

A helpful way to see it is:

• potius = rather
• quam = than

The two compared words are in the same case here, both accusative, because both depend on spectare.

No. Potius is an adverb, not an adjective.

That means it does not change its form to match a noun. It simply modifies the comparison:

• potius quam = rather than

So it is not agreeing with iustitiam or iram; it is just helping express the contrast between them.

Because Latin word order is much more flexible than English word order.

Placing the finite verb at or near the end is very common in Latin prose. Here the order:

• Bonus iudex iustitiam potius quam iram spectare debet

lets the sentence build toward the main statement at the end: the good judge ought...

This order also keeps the contrast iustitiam ... iram nicely together.

In English, we usually need a more fixed order, but in Latin the endings show the grammar, so the author has more freedom.

Because Classical Latin has no articles.

So bonus iudex can mean:

• a good judge
• the good judge
• sometimes even any good judge

The exact sense depends on context.

This is one of the biggest differences from English: Latin often leaves definiteness unstated.

Yes. Iudex is a noun that can refer to a male or female judge, depending on context.

In this sentence, bonus is masculine, so it points to a male judge or uses the masculine form generically. If the judge were clearly female, you would expect:

• bona iudex

The noun iudex itself stays the same in the nominative singular; the adjective shows the gender.

A very helpful reading is:

• Bonus iudex = a good judge
• iustitiam = justice
• potius quam iram = rather than anger
• spectare debet = ought to regard / must consider

So the grammar falls into place as:

[Subject] + [Object 1] + [comparison with Object 2] + [infinitive + finite verb]

That is often the easiest way for an English speaker to process a Latin sentence without getting lost in the word order.
