Meaning & readings

husk, nut shell

On’yomi カク、コク、バイ
Kun’yomi から、がら

Origin

The character combines a sound hint on the left with a meaning component on the right. The left part, 壳, provides a rough pronunciation guide for the character. The right part, 殳, is a classifier that traditionally relates to weapons or striking tools, but here it functions as a marker for the general category of hard outer coverings. Together, these components create a character that visually and phonetically represents the hard shell or husk that encloses seeds, nuts, and other things—the outer protective layer you need to break through.
