17 Chinese Grammar Points about 也 (Yě)
1. 也"also"
也， meaning "also", is an adverb. It can be placed before 是, but it cannot precede a noun or a pronoun.
2. 而且 + 也/还: "Not only-but also-"
也 or 还 can be used to add additional information about the subject.
3. 也 vs. 还
When 2 clauses do not share the same subject, 也 becomes necessary. 还 cannot be used for sentences with more than one subjects.
4. 又 vs 也
又 is defined as 'again', it indicates the repetition of an action or event that already took place. 也 implies a different subject did the same thing.
5. 也 vs. 都
也 means "also". 都 means "all". Both are adverbs. They can be placed before 是, but they cannot precede a noun or a pronoun.
6. 也好/也罢: "Whether-or not"
When used together, people would normally associate 也好 to a positive choice or action and 也罢 to a negative one, and the sequence is always 也好 first, followed by 也罢.
7. 即使-也: "Even if"
When 也 appears in a sentence with 即使， it does not have a stand-alone meaning, and should not be literally translated as 'also'. 即使-也 is a pair that means 'even if'; it is interchangeable with 就是-也.
8. 除了-以外，也: To show 'inclusion'
1. This expression can be used to show 'inclusion', the main sentence should have 也. Usually, what follows 除了 is the known information; the main clause is used to give additional information. 2. When the 2 parts of the sentence refer to different subjects, only 也 can be used (and 还 cannot).
9. 什么/谁 + 也 + 没
Interrogative pronouns can be placed before 也+没 for meaning 'nobody','nothing', etc.

连...也/都 is used as an emphatic expression to indicate an extreme situation. Either 也 or 都 can be used before the verb in the main sentence.
11. 一点儿也不: "Not in the least"
一点儿也不 is used to express complete negation, "not at all, Not in the least". This is an emphatic expression.
12. 怎么也+不: "No matter what"
怎么也+不: "No matter what" used to emphasize that something is always true, or that someone must do something.
13. 既不…也不: "Neither…nor"
The conjunction 既不-也不 means "neither…nor".
14. 再也不-了: "Never again"
再也不-了 is a strong expression, which means 'never again'. 了 is necessary to show a change of situation.
15. 再也 + 没有 "never,no-again"
再也，meaning 'again', can be placed in front of 没有 to emphasize the negation. 再也没有-过 indicates that something has stopped happening since a certain point. 再也没有+noun+了 implies 'no longer' and 了 is not optional.
