The left side 亻 (にんべん) means “person,” and the right part 氏 (テイ) gives sound. Together, they suggest a person who is near the ground — hence “low.” It can describe height, tone, status, or modesty.

For example, 低姿勢ていしせい means “humble attitude.”

気温きおんが 低ひくくなってきました。
The temperature has dropped.

彼かれは 低姿勢ていしせいで 有名ゆうめいです。
He is known for his humble attitude.

The kun-yomi “ひくい” means “low” and is used for describing height or rank. The on-yomi “テイ” is common in compound words like 最低さいてい (lowest) or 低下ていか (decline).
