Learn Hardcore Chinese: wǒmen měitiān dōu hěn máng, dànshì yě hěn gāoxìng. - We are busy every day, but also very happy.

In the pattern 每天都, 都 emphasizes regularity: “every day (we) are [busy].” It works like “each/every time, it’s the case that...”
With a group subject, 都 can also mean “all.” In 我们每天都很忙, the most natural reading is triggered by 每天 (“every day”).
If you specifically want to stress “all of us,” make it explicit: 我们大家每天都很忙 or 我们每个人每天都很忙.

Why is 很 (hěn) before 忙 and 高兴? Does it literally mean “very”?

Before adjectives, 很 often functions as a default degree marker that makes the sentence sound natural. It frequently doesn’t mean strongly “very”; it can just mean “is/are [adj].”
So 很忙 can simply be “busy,” not necessarily “very busy,” unless context or intonation adds strength.
To clearly say “very,” use stronger words like 非常, 特别, 挺 (…的), 真, etc.

Can I omit 都 or 很?

Omit 都: 我们每天很忙 is fine; it just loses the “every single day / invariably” feel that 每天都 gives.
Omit 很: 我们每天都忙 is grammatically possible, but bare adjectives as predicates can feel abrupt or contrastive. In everyday speech, including 很 is the safer, more natural default: 我们每天都很忙.

Where does 也 (yě) go and what does it add?

也 comes after the (understood) subject and before the predicate: 但是我们也很高兴 or (with the subject omitted) 但是也很高兴.
It means “also/too,” adding another coexisting fact: besides being busy, we’re also happy.
Don’t say 很也高兴; the order is 也很
- adjective.

Why use both 但是 (dànshì) and 也 (yě)? Isn’t that redundant?

但是 introduces a contrast (“but/however”).
也 adds an additional property (“also”).
Together they convey: “We’re very busy, but we’re also happy.” Without 也, it’s just a contrast; with 也, it’s “in addition, too,” softening the contrast and highlighting coexistence.

Could I use 可是, 不过, or 但 instead of 但是?

Do I need to repeat 我们 after 但是?

No. Chinese often drops a repeated subject when it’s clear from context.
Both are correct: ……，但是我们也很高兴。 and ……，但是也很高兴。 The second simply omits the repeated 我们.

Why is 每天 before 都? Can I say 我们都每天很忙?

都 applies to whatever appears before it. The pattern is “(Subject) + (Time/Range) + 都 + Predicate.”
我们每天都很忙 is correct: 都 scopes over 每天 (“on every day, [it’s true that]...”).
我们都每天很忙 is unnatural; keep 都 immediately after the element(s) it quantifies.

Can I move 每天 to the front?

Yes: 每天我们都很忙 is fine and slightly emphasizes “every day.”
Time expressions typically go before the predicate in Chinese. End position (……很忙每天) is not natural.

Are 忙 and 高兴 adjectives or verbs? Do I need 是?

They are adjectives, but Chinese adjectives can function as stative predicates (like verbs).
Don’t use 是 directly before a predicate adjective: say 我们很忙, not 我们是忙.
You can use 是 for emphasis in a contrastive pattern: 我们每天是很忙，但是也很高兴 (“We are indeed busy, but also happy”).

Could/Should I use 虽然 … 但是 … here?

Does 也 here mean “still”? Should I use 还是 instead?

也 = “also/too.” It adds another fact.
还是 = “still/nevertheless” (in this use), implying an unexpected persistence: ……，但是还是很高兴 = “but (we’re) still happy.”
Both are possible with slightly different nuance:
- 也很高兴: “also happy (in addition to being busy).”
- 还是很高兴: “still happy (despite being busy).”

What’s the difference between 高兴 and 开心?

Both mean “happy,” and are often interchangeable here.
Nuance:
- 高兴: glad/pleased (often momentary or about a cause).
- 开心: happy/cheerful, having fun.
You could say ……也很开心 with a very similar meaning.

What about 每天 vs 天天 vs 每一天?

Could I say 又忙又高兴?

Yes. 又…又… links two adjectives: 我们每天又忙又高兴 = “We’re both busy and happy every day.”
This frames the two states as coexisting, without the explicit contrast that 但是 gives.

Any tone-sandhi tips in this sentence?

Third tone before third tone changes to a rising second on the first syllable:
- 也很 (yě hěn) is pronounced like “yé hěn.”
很忙 is 3-2, so no 3→2 change needed.
Others stay as marked: 每天 (měitiān), 都 (dōu), 但是 (dànshì), 高兴 (gāoxìng).

Is the comma ， before 但是 okay?

Yes. Chinese commonly links two related clauses with a comma: ……，但是…….
In more formal writing, a semicolon ； can also be used, but the comma is very common and correct.
