+### Grammar
+- **Cause and Effect with (と)**: Used to show a direct cause and effect relationship, similar to "if" or "when" in English, but with a strong sense of certainty that the result will follow the cause.
+	- **Formation**:
+		- **Verb (dictionary form) + と**
+	- **Key Usage**: The result in the second clause is a natural or inevitable consequence of the action in the first clause.
+	- **Examples**:
+		- *うまくいくと, いいですね* - If things go smoothly, it'll be good.
+		- *ご飯を食べると、ねむくなります。* - If I eat lunch, I'll then become sleepy.
+
+- **Connecting Verbs with (てから)**: This pattern is used to show that one action takes place after another action is completed. It clarifies the sequence of events.
+	- **Formation**:
+		- **Verb (て-form) + から**
+	- **Key Usage**: Emphasizes the completion of the first action before the second one begins.
+	- **Examples**:
+		- *シャワーを浴びてから、ご飯を食べます* - After I take a shower, I will eat.
+		- *宿題が終わってから、寝ます。* - After I finish my homework, I will sleep.
+
+- **Transitive (他動詞) and Intransitive (自動詞) Verbs**: This is a fundamental concept in Japanese grammar that distinguishes between verbs that require a direct object and those that do not.
+	- **Transitive Verbs (他動詞 - tadoushi)**:
+		- An action done *by* a subject *to* an object.
+		- The object is marked with the particle **を (o)**.
+		- *Example: 私が電気**を**つけます。* (I turn on the light.)
+	- **Intransitive Verbs (自動詞 - jidoushi)**:
+		- An action that happens *on its own*. There is no direct object.
+		- The subject is marked with the particle **が (ga)**.
+		- *Example: 電気**が**つきます。* (The light is on.)
+	- **Common Pairs**: Many verbs come in pairs. Learning them together is an effective way to master their usage.
+		- 開ける (akeru - to open) / 開く (aku - to be open)
+		- 閉める (shimeru - to close) / 閉まる (shimaru - to be closed)
+		- 入れる (ireru - to put in) / 入る (hairu - to enter)
+		- 出す (dasu - to take out) / 出る (deru - to go out)
+		- 消す (kesu - to turn off) / 消える (kieru - to disappear)
