Common Contexts
You will frequently see "正常" used to describe health conditions (e.g., body temperature, blood pressure), machine operations (e.g., computers, vehicles), and social or psychological states.

- 正常に動作する (せいじょうにどうさする): to operate normally

Nuances and Tips
"正常" is more formal and objective than casual words like "普通" (ふつう). It often implies that something meets a defined standard or expected function. Be careful not to confuse it with "正常化" (せいじょうか), which means "normalization" or the process of becoming normal.
Common Mistake
Learners sometimes use "正常" to describe subjective feelings or opinions, but it is better suited for objective states or measurable conditions.
