zhěnggè fángjiān hěn gānjìng.

整个 means the whole, the entire, or all of.

It is made up of:

• 整 = whole, complete
• 个 = a very common measure word

So 整个房间 means the whole room or the entire room.

In this sentence, it emphasizes that the room is clean everywhere, not just in one part.

In Mandarin, nouns are often connected to modifiers through a measure word or classifier. In 整个, 个 is part of a very common fixed pattern meaning the whole + noun.

So:

• 整个房间 = the whole room
• 整个城市 = the whole city
• 整个世界 = the whole world

Even though 房间 has its own classifier in some contexts, 整个 is a very natural and common phrase on its own.

Because Chinese usually puts modifiers before the noun.

So the structure is:

• 整个
  • 房间
• whole
  • room

This is similar to English phrases like the whole room or the entire room, where the describing word also comes before the noun.

Not always.

In a sentence like 房间很干净, 很 often does not strongly mean very. It is frequently used before adjectives when the adjective is the main predicate of the sentence.

So:

• 房间很干净 often just means The room is clean
• not necessarily The room is very clean

This is one of the most important things for English speakers to learn: in Mandarin, adjectives can act like predicates, and 很 is often used to make the sentence sound natural.

Grammatically, it is possible in some contexts, but it often sounds incomplete, contrastive, or unnatural by itself.

Compare:

• 整个房间很干净。 = The whole room is clean.
• 整个房间干净。 = can sound like As for the whole room, it is clean or like part of a comparison/contrast.

So for a simple descriptive sentence, 很 is the normal choice.

It is usually called an adjective in learner materials, but in Mandarin it behaves a bit differently from English adjectives.

干净 can directly function as the predicate of a sentence:

• 房间很干净。
• 桌子不干净。

So in practice, Mandarin adjectives often act a little like stative verbs. That is why Chinese does not need a separate word like is in this sentence.

English:

• The room is clean.

Chinese:

• 房间 很干净.

There is no verb corresponding to is here.

Because Mandarin usually does not use 是 before adjectives.

English says:

• The room is clean.

But Chinese normally says:

• 房间很干净。

If you say:

• 房间是干净。

that sounds unnatural in normal speech.

Use 是 mainly when linking nouns or noun phrases, not adjectives:

• 他是老师。 = He is a teacher.

But with adjectives like 干净, Chinese normally just uses the adjective directly, often with 很.

房间 means room in a general sense.

It can refer to:

• a bedroom
• a hotel room
• a room in a house
• a room in a building

It does not automatically mean bedroom only. The exact meaning depends on context.

• 房间很干净 = The room is clean.
• 整个房间很干净 = The whole room is clean / The entire room is clean.

Adding 整个 gives extra emphasis. It suggests that all parts of the room are clean, not just one area.

For example, if the floor, desk, bed, and corners are all clean, 整个房间很干净 fits especially well.

You would usually use 不 before 干净:

• 整个房间不干净。 = The whole room is not clean.

You can also soften it:

• 整个房间不太干净。 = The whole room is not very clean.

That often sounds more natural and less blunt than a direct 不干净.

Yes. Different words change the strength or tone:

• 整个房间很干净。 = The whole room is clean.
• 整个房间非常干净。 = The whole room is very clean.
• 整个房间真干净。 = The whole room is really clean.
• 整个房间特别干净。 = The whole room is especially clean.

So 很 is the neutral, basic choice.

It is pronounced:

• 整个 — zhěnggè
• 房间 — fángjiān
• 很 — hěn
• 干净 — gānjìng

A few helpful notes:

• 个 in 整个 is pronounced with a neutral tone here: gè
• 间 in 房间 is pronounced jiān
• 干净 has first tone + fourth tone: gān jìng

So the full sentence is:

Zhěnggè fángjiān hěn gānjìng.

Not in natural English.

A more natural translation is:

• the whole room
• the entire room

English usually does not say all the room in this situation. So while 整个 carries the idea of all of it, the best translation here is the whole room.

Yes, absolutely.

整个房间很干净。 is a normal, natural sentence. It sounds like something a person might say when describing a room in a house, hotel, classroom, or apartment.

It is a good example of a basic Mandarin pattern:

noun phrase + 很 + adjective

For example:

• 这个地方很安静。 = This place is quiet.
• 他的房间很大。 = His room is big.
• 整个房间很干净。 = The whole room is clean.
