+## Conditional Forms - *Added: 2026-01-28*
+### 1. The ~eba (~えば) Form
+
+This is often called the **"Logical If."** Use this when focusing on the condition required to achieve a specific result.
+
+- **How to form it:** **Verbs:** Change the final _~u_ sound to _~e_ and add _ば_. (e.g., _Iku_ → _Ikeba_)
+    
+    - **I-Adjectives:** Drop the final _~i_, add _~kereba_. (e.g., _Samui_ → _Samukereba_)
+        
+- **The Vibe:** It’s very "If A happens, then B will definitely follow." It is often used for instructions, proverbs, or mathematical certainties.
+    
+
+### 2. The Nakereba (なければ) Form
+
+This is simply the **negative version of ~eba**. It translates to **"If "something" does not happen."** 
+
+- **How to form it:** Take the negative (_nai_) form of a verb, drop the _~i_, and add _~kereba_.
+    
+- **Example:** _Tabenai_ (don't eat) → _Tabenakereba_ (If I don't eat).
+    
+- **Common Use:** You’ll see this in the phrase for "must": _~nakereba narimasen_ (lit: "If you don't do it, it won't be okay").
+- Can also stick "よかった" after it to mean "I wish I "
+    
+
+---
+
+### 3. The ~tara (~ら) Form
+
+This is the **"Conversational If."** It is the most versatile and common conditional in spoken Japanese.
+
+- **How to form it:** Take the **past tense** of the verb/adjective and add _~ra_.
+    
+    - **Verbs:** _Itta_ (went) → _Ittara_ (If/when I go).
+        
+    - **Adjectives:** _Samukatta_ (was cold) → _Samukattara_ (If it's cold).
+        
+- **The Vibe:** It can mean "if" (hypothetical) or "when" (temporal). It’s very safe to use in almost any casual situation.
+    
+#### What is the negative of ~tara?
+
+The negative form is **~nakattara**.
+
+- **How to form it:** Take the negative past tense (_~nakatta_) and add _~ra_.
+    
+- **Example:** _Ikanakatta_ (didn't go) → _Ikanakattara_ (If I don't go/If I hadn't gone).
+
+### Examples
+- 僕はもっと勉強すればよかった
+	- I should have studied more

 ## Describing Body States - *Added: 2026-01-21*
 When describing a person's current physical state (like being slim or overweight), it's common to use the `～ている` form of a verb. This describes the result of a change that has occurred and is ongoing. This is different from using a simple い-adjective, which often describes the inherent quality of an object.
