+### Virtual Methods
+
+The `virtual` keyword marks methods as dispatchable through the vtable, enabling polymorphic behavior:
+
+```mist
+pub class Animal
+{
+    str& name;
+
+    pub constructor(str& name)
+    {
+        self.name = name;
+    }
+
+    pub virtual void speak(&self)
+    {
+        println!("...");
+    }
+}
+```
+
+When a method is marked `virtual`, it can be overridden in subclasses and will be dispatched dynamically at runtime through the vtable. Non-virtual methods are called statically.

+Methods marked `override` are automatically virtual if the parent method is virtual. The semantic analyzer validates that overridden methods match the parent's signature.

 ### Implementations
 
 You can implement directly on the class body:
