black ink, India ink, ink stick, Mexico

Kun’yomi すみ
Nanori すの

Origin

The character combines earth () at the bottom with black () at the top. The black component provides both a sound hint for how to pronounce the character and a clue to its meaning — ink is made from black pigment mixed with a binder. The earth radical at the base may suggest the mineral or earthy origins of ink materials. Together, these components evoke the dark, solid ink sticks used for writing and painting in East Asia.
