 # Supplementary Notes
-## Explaining Things about our body
+## Describing Body States
-When Explaining things about ours or others body, we should use verbs, instead of い-adj. い-adj is used for describing things, not people.
+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.
 
-- 瘦せる -> やせる -> To lose weight
+- 痩せる -> やせる -> To become slim
-	- 瘦せっている -> To exist in a slim state
+	- 痩せている -> (He/She) is slim (existing in a slim state)
-	- 
+- 太る -> ふとる -> To become fat
-- 太る -> ふとる -> To get fat
+	- 太っている -> (He/She) is fat (existing in a state of being fat)
-	- 太っている -> To exist in a state of being fat
+
-	- 太い -> ふとい -> 
+Compare this with an い-adjective like `太い` (futoi), which means "thick" or "fat." You would use this for objects or specific body parts, not typically to describe a person's overall state in a polite context.
+- e.g., `太い腕` (futoi ude) -> A thick arm.
