Sutdae-sal | A Changho Joined with Broken Slats

Wanja-sal | A Pattern Overflowing with Meaning
In the previous piece, I wrote that aja-sal scattered because it had no meaning. Wanja is the opposite. It has too much meaning.

Manja-sal and Man-sal Are Different Changho
Two names that meet over a one-syllable difference Say "man-sal" meaning jeongja-sal, and people sometimes hear it as "manja-sal" instead. Written in Hangul, they're 만자살 and 만살 — close enough that the mix-up makes sense. But the two have different patterns, and point at different things from the very start.

Bit-sal | A Changho Joined with Slats Set on the Diagonal
Bit-sal is a changho where the slats are tilted 45° and crossed, so that slat meets slat off-axis to form a diamond grid. Unlike se-sal and jeongja-sal, joined from slats standing straight, every line in this changho runs on a diagonal.

Se-sal (細살) | A Changho Set with Fine Slats, Packed Close
Se-sal is a changho built by standing vertical slats close together, while the horizontal slats are bundled in small groups at three levels — top, middle, and bottom. It was the most widely used of all lattice joineries, hung everywhere from ordinary home doors to temple halls and palaces.

Jeongja-sal | A Changho Joined into the Character 井
It's called jeongja-sal because it resembles the character 井 (jeong). In Korean it's also called umul-sal ("well lattice") — join the same grid onto a ceiling and you get umul-banja, umul-cheonjang ("well ceiling"). It's a rare case where the Hanja name and the native Korean name both survived side by side.
