1. Explain it simply
也 means 'also / too' and always comes AFTER the subject, BEFORE the verb.
It never goes at the end of the sentence like English 'too' does.
2. Show examples
我也是学生。
Wǒ yě shì xuésheng.
I am also a student.
Subject + 也 + verb
他也喜欢中文。
Tā yě xǐhuan Zhōngwén.
He also likes Chinese.
也 before the verb 喜欢
你们也去吗？
Nǐmen yě qù ma?
Are you all going too?
Works in questions the same way
3. Share a tip
Never put 也 at the end of a sentence - unlike English 'too', it always sits before the verb.
