When do I use 也 vs 还?

Use 也 when you mean 'too' or 'as well' for the same predicate, often with a different subject (e.g., '你去了，我也去了' – 'You went, I went too'). Use 还 when you want to add another action or item, typically for the same subject (e.g., '我去了公园，还去了商店' – 'I went to the park and also went to the store'). 还 can appear with a different subject when the second clause adds extra cumulative information.

Can 还 be used with a different subject?

Yes, but only when the second clause provides additional, often contrasting, information to the discourse. For example, '他喝啤酒，我还喝红酒' – 'He drinks beer, and I (in addition) drink red wine.' This is correct because it adds a new fact, not a parallel 'too'. For a pure 'likewise' meaning with the same predicate, you must use 也.

Is it wrong to say '我吃了苹果，也吃了香蕉'?

It is not wrong, but it emphasizes that the same subject does both actions in a parallel sense (like 'I ate apples and I also ate bananas'). However, for simple addition without emphasis on parallelism, 还 is more natural. Both are grammatically correct; the choice depends on nuance.

How do I express 'neither' or 'also not'?

Use 也 in negative sentences: '他不喜欢咖啡，我也不喜欢' (He doesn't like coffee, I don't either). 还 in negative sentences usually means 'still not' (e.g., '他还没来' – He hasn't come yet), not 'neither'.

也 vs 还 (yě vs hái): additive adverbs “also” and “in addition”

也 (yě) means “also” or “too” and is used to say that the same predicate applies to a new subject or that a subject does the same action as another. 还 (hái) means “in addition” or “moreover” and usually adds a new predicate for the same subject, but it can also add a cumulative fact about a different subject when the discourse adds extra information. The choice depends on whether you are emphasizing parallelism (也) or addition (还).

也 and 还 both translate to “also” in English, but they serve different functions. 也 marks parallelism: it says the same action or state applies to another subject (e.g., “I like coffee, and she likes coffee too”) or that one subject does the same thing as another. 还 marks addition: it adds a new action or item, typically for the same subject (e.g., “I ate apples and also ate bananas”), but it can also add a cumulative fact about a different subject when the new clause provides extra, often contrasting, information (e.g., “He bought a house, and I also bought a car”). The main rule is that 也 is for “likewise” while 还 is for “moreover / in addition”.

Quando usar cada um

也yě

also, too

Use 也 when you want to say that a predicate (verb phrase) that applies to one subject also applies to another subject, or that one subject does the same action as another. It often appears in constructions like 'A 做 X, B 也做 X' (A does X, B does X too). 也 can also be used for the same subject when the meaning is 'as well' in a parallel sense (e.g., '他也会说英语' – He can also speak English, implying in addition to something else).

也 often carries a nuance of symmetry or shared quality between the subjects. In negative sentences, 也 can mean 'neither' (e.g., '我也不想去' – I don't want to go either).

还hái

also, in addition

Use 还 to add another action, item, or fact to an already stated one. It is most common with the same subject adding a new predicate (e.g., '我吃了苹果，还吃了香蕉' – I ate apples and also ate bananas). 还 can also be used with a different subject when the second clause presents additional information that is cumulative or contrasting (e.g., '他买了房子，我还买了车' – He bought a house, and I (in addition) bought a car). In such cases, 还 still functions as an additive adverb, not a parallel 'too'.

还 has other meanings (still, yet, even), but in the additive sense it always implies one more thing beyond what has been mentioned. It cannot be used to replace 也 in a pure 'likewise' context (e.g., '他喜欢茶，我也喜欢茶' – not 还).

Visão geral

	也	还
Core meaning	Likewise (same predicate applies to another subject)	In addition (add new predicate or item)
Typical subject pattern	Often different subjects sharing one predicate	Often same subject with another predicate
Can appear with different subjects and a new predicate?	Yes (parallelism: A does X, B does X too)	Yes, but only when the second clause adds a cumulative fact to the discourse (e.g., 'I did X, and you did Y in addition')
Word order	Subject + 也 + Verb (etc.)	Subject + 还 + Verb (etc.)
Negative equivalent	也不 (also not / neither)	还不 (usually 'still not' or 'not yet'; additive negative rare)

Exemplos

也
他是老师，我也是老师。
Tā shì lǎo shī, wǒ yě shì lǎo shī.
He is a teacher, and I am also a teacher.
Same predicate (being a teacher) applies to different subjects – 也 is used.
还
我吃苹果，还吃香蕉。
Wǒ chī píng guǒ, hái chī xiāng jiāo.
I eat apples and also eat bananas.
Same subject adds another action – 还 is appropriate.
还
他买了房子，我还买了车。
Tā mǎi le fáng zi, wǒ hái mǎi le chē.
He bought a house, and I also bought a car (in addition).
Different subject, but 还 adds a cumulative fact – valid usage.
也
我不喜欢咖啡，她也不喜欢。
Wǒ bù xǐ huan kā fēi, tā yě bù xǐ huan.
I don't like coffee, and she doesn't either.
Negative parallel – 也 used for 'neither'.
还
我们吃了晚饭，还看了电影。
Wǒ men chī le wǎn fàn, hái kàn le diàn yǐng.
We had dinner and also watched a movie.
Same subject adds another activity – 还.
也
他吃苹果，他也吃香蕉。
Tā chī píng guǒ, tā yě chī xiāng jiāo.
He eats apples and also eats bananas.
Same subject, but 也 here implies 'as well' – possible, though 还 is more common for addition. 也 feels more like saying 'in the same manner'.

Erros comuns

Using 还 for a different subject when the meaning is 'too' with the same predicate: '他喜欢茶，还喜欢咖啡' means 'He likes tea and also likes coffee' (same subject). For different subjects (e.g., 'He likes tea, I also like tea'), use 也.
Using 也 instead of 还 to add a new action for the same subject: '我吃了苹果，也吃了香蕉' is acceptable but may sound like you are emphasizing the shared predicate rather than addition; 还 is more natural for simple addition.
Putting 还 before the subject: '还我吃香蕉' is incorrect. 还 must follow the subject: '我还吃香蕉'.
Confusing 还 with 也 in negative sentences: '他也不去' means 'He is also not going' (neither), while '他还不去' means 'He still isn't going' (different meaning). Use 也 for 'neither'.
