Meaning & readings

plump, thick, big around

On’yomi タイ、タ
Kun’yomi ふと.い、ふと.る
Nanori おお、たか、ひろ

Origin

This character combines "big" (大) with a dot below it to show something that is not just large but thick or swollen outward. The dot acts like a visual marker emphasizing the rounded, bulging quality of something plump or wide around, as opposed to merely tall or long. By adding this small dot to the character for "big," the original meaning expanded to specifically capture the idea of thickness or fullness in width rather than just size in general.
