Si discipulus superbus est, minus discit; si docilis et modestus est, celerius discit.

Because it contains two separate conditional statements:

• Si discipulus superbus est, minus discit
• si docilis et modestus est, celerius discit

Each si means if and introduces its own condition. Latin often repeats si just as English would repeat if in a sentence like:

• If a student is proud, he learns less; if he is teachable and modest, he learns more quickly.

Latin often leaves out a word when it is easy to understand from context. In the second clause, the subject is still discipulus:

• si docilis et modestus est = if he/the student is teachable and modest

So Latin does not need to repeat discipulus. English can do something similar:

• If a student is proud, he learns less; if teachable and modest, he learns more quickly.

The Latin is perfectly natural.

They are adjectives describing the subject discipulus. Because discipulus is:

• masculine
• singular
• nominative

the adjectives must match it in gender, number, and case:

• discipulus superbus est
• discipulus docilis et modestus est

These are called predicate adjectives, because they go with est and describe what the student is.

Because Latin, like English, often uses a form of to be to link a subject with an adjective:

• discipulus superbus est = the student is proud
• docilis et modestus est = he is teachable and modest

Here est is the 3rd person singular present of esse (to be).

This is a simple present general condition. It expresses a general truth or usual result, not a specific future event.

So the idea is:

• If a student is proud, he learns less.
• If he is teachable and modest, he learns more quickly.

Latin commonly uses the present indicative in both parts for this kind of statement.

Because the sentence is stating a general principle, not predicting one particular future event.

• discit = learns

Latin often uses the present tense where English also uses the present for general truths:

• If water boils, it becomes steam
• If a student is proud, he learns less

So discit is exactly what we would expect.

Minus here is an adverb, meaning less.

It modifies discit:

• minus discit = he learns less

This is not an adjective agreeing with a noun. It is describing how much he learns.

You can think of it as parallel to English less in:

• He studies less
• He learns less

Because celerius is the comparative adverb from celer (quick).

The pattern is:

• adjective: celer = quick
• adverb: celeriter = quickly
• comparative adverb: celerius = more quickly

So:

• celerius discit = he learns more quickly

A learner might expect celeriter, but celerius is specifically the comparative form.

Good question. Latin comparatives do not always need an explicit comparison word like quam (than).

Here the comparison is understood from context:

• a proud student learns less
• a teachable and modest student learns more quickly

In other words, the sentence is contrasting the two kinds of student. Latin can leave that comparison implicit.

If the sentence wanted to state the comparison more explicitly, it could do so, but it is not necessary here.

Latin word order is more flexible than English word order because Latin relies heavily on endings to show grammatical relationships.

So:

• Si discipulus superbus est, minus discit
• Si superbus discipulus est, minus discit

would still be understandable, though the original is the more natural and straightforward arrangement.

In this sentence, the order is fairly clear and balanced:

1. condition
2. result
3. condition
4. result

That balanced structure helps the contrast stand out.

Discipulus is nominative singular.

You can tell because it is the subject of both est and discit. In dictionary form, discipulus is a second-declension masculine noun, and its nominative singular ends in -us.

So here:

• discipulus ... est = the student is ...
• discipulus ... discit = the student learns ...

Even when the noun is omitted in the second clause, it is still understood as the same nominative subject.

The semicolon separates two closely connected but independent parts of the sentence.

The two halves are parallel:

• si discipulus superbus est, minus discit
• si docilis et modestus est, celerius discit

A semicolon is a nice punctuation choice in English and in edited Latin texts because it shows a strong pause and highlights the contrast between the two conditions.

Yes. Et simply means and:

• docilis et modestus = teachable and modest

Latin could sometimes use -que attached to the second word:

• docilis modestusque

That would also mean teachable and modest. In this sentence, et is the straightforward and easy choice.

Yes. It is built in a very balanced, contrastive way, which is common in Latin moral or instructional writing.

It sets up:

• one negative character trait → worse learning
• two positive character traits → better learning

The repetition of structure makes it memorable:

• si ... est, ... discit
• si ... est, ... discit

That kind of symmetry is very typical of polished Latin prose.
