Meaning & readings

-proof, enduring

On’yomi タイ
Kun’yomi た.える
Nanori たえ

Origin

The character combines two parts. On the left, 而 is a sound hint that helps indicate how to pronounce the character (roughly "ji" or "ri" in older Chinese). On the right, represents a small unit of measurement or something small and precise. Together, these parts came to mean something that can withstand or endure — the idea is that something small and measured can persist against pressure or stress. Over time, this extended to mean "proof against" or "resistant to," as in water-proof or heat-proof.
