1. あなた: You

「あなた」 means you. It is a second-person pronoun, but in Japanese, people often avoid using it directly. Instead, they might use the person’s name or title (like “sensei” or “Tanaka-san”
Example:
あなたは学生ですか?
Are you a student?
Note: While grammatically correct, using 「あなた」 can sometimes sound distant or too direct, especially in close relationships. Use it carefully.
2. かも: Maybe / might be

「かも」 is a casual and shortened form of 「かもしれない」, which means might or may. It expresses uncertainty.
Structure:
Noun/Verb/Adjective + かも(しれない)
Examples:
明日は雨かも。
It might rain tomorrow.
彼は学生かも。
He might be a student.
Note:「かも」 is informal. In polite speech, use 「かもしれません」.
3. 「いい」 Conjugation: Good — adjective form

「いい」 is an irregular い-adjective, meaning good. Its past and negative forms are not based on 「いい」 but on its older form 「よい
Conjugation:
- Present: いい (good)
- Negative: よくない (not good)
- Past: よかった (was good)
- Past negative: よくなかった (was not good)
Examples:
この本はいいね。
This book is good.
その映画はよくなかった。
That movie wasn’t good.
Note: Even though people say 「いい」, they use 「よ」 in the negative and past forms.
4. ならない / いけない: Must not / Have to


Both 「~てはならない」 and 「~てはいけない」 mean must not do something. They show prohibition.
On the other hand, 「~なければならない」 or 「~なければいけない」 means must do something.
Prohibition:
- Verb (て-form) + はいけない / はならない
ここでタバコを吸ってはいけません。
You must not smoke here.
Obligation:
- Verb (ない-form) + ければならない / ければいけない
明日、学校へ行かなければならない。
I must go to school tomorrow.
Note:「ならない」 is slightly more formal than 「いけない」.
- In casual speech, people often say 「なきゃ」 or 「なくちゃ」 instead.
