正常

正常 (zhèng cháng) means 'normal' in English, indicating something that is usual, standard, or as expected. It often contrasts with something unusual or abnormal.

The character 正 (zhèng) originally meant 'upright' or 'correct,' and 常 (cháng) means 'usual' or 'customary.' Together, they form a term that describes something that follows the standard or expected pattern.

正常 is commonly used in daily conversation to describe conditions, behaviors, or situations that are within the usual range. For example, it can be used to say that a person's temperature is normal or that a system is operating normally. It is also used in medical, technical, and social contexts to indicate what is considered standard or typical.
