Колледж уже открыт.

In Russian, the verb to be is usually omitted in the present tense.

So where English says The college is already open, Russian simply says:

• Колледж уже открыт

This is completely normal. Russian does use forms of to be in the past and future, but not usually in the present in sentences like this.

Открыт is the short form, and that is the normal form when it is used as the main predicate of the sentence:

• Колледж уже открыт = The college is already open

Открытый is the full form, which is more often used before a noun:

• открытый колледж

That would not normally mean the same thing here. It would sound more like an open college as a description, not the college is open.

So after the subject, Russian usually prefers the short form:

• дверь открыта
• магазин открыт
• окно открыто

Yes. Открыт agrees with колледж, which is masculine singular.

Short forms change depending on gender and number:

• masculine: открыт
• feminine: открыта
• neuter: открыто
• plural: открыты

So:

• Колледж открыт
• Школа открыта
• Окно открыто
• Двери открыты

Because колледж is masculine, открыт must also be masculine.

In grammar terms, it is often described as a short-form passive participle of открыть.

But for a learner, the most useful thing is this:

• it behaves a lot like a predicate adjective
• it describes a state
• it often translates naturally as open

So in this sentence, you can think of it as meaning that the college is in the state of being open.

That is why Колледж уже открыт focuses on the result or current state, not just the action of opening.

Уже means already.

It shows that the state is true by now, perhaps earlier than expected or by a certain point in time.

So:

• Колледж открыт = The college is open
• Колледж уже открыт = The college is already open

In this sentence, уже comes before открыт, which is a very natural placement.

Yes, Russian word order is flexible, but different orders change the emphasis.

The neutral order here is:

• Колледж уже открыт

Other orders are possible, for example:

• Уже колледж открыт
• Колледж открыт уже
• Открыт уже колледж

But these sound more marked, literary, or context-dependent.

For most learners, Колледж уже открыт is the safest and most natural version.

This is a very useful distinction.

• Колледж уже открыт focuses on the current state: the college is already open.
• Колледж уже открылся focuses more on the event of opening: the college has already opened.

In many contexts they can be close in meaning, but the nuance is different:

• открылся = the opening happened
• открыт = the result is now true

English sometimes makes the same distinction:

• The college has already opened
• The college is already open

Колледж is in the nominative singular because it is the subject of the sentence.

A simple breakdown:

• Колледж — noun, nominative singular, masculine
• уже — adverb
• открыт — short-form predicate agreeing with the masculine singular subject

So the structure is basically:

• [subject] + [adverb] + [predicate]

The stress is on the second syllable:

• колле́дж

A rough English approximation would be something like ka-LYEDZH, but with Russian sounds.

Also:

• дж is pronounced like the j in judge
• the first о is reduced in unstressed position, so it does not sound like a clear English o

And открыт is stressed as:

• откры́т

It can mean either, depending on context.

Russian открыт can describe a present state such as:

• the college is open for visitors/students
• the college has been opened and is now functioning

Context tells you which meaning is intended.

For example:

• on a sign or schedule, it probably means open now
• in news or historical context, it could mean has now been opened

So the sentence itself is a little broad, just like English The college is already open can be.
