Jagged means with rough uneven points along an edge. A jagged edge, jagged rocks, jagged glass.
The unevenness is the point — a jagged edge is irregular where a serrated one is regular, which is the difference between broken and made. Of a line on a graph it means sharply up and down. Note jag, meaning a sharp projection; and that jagged has two syllables, JAG-id.
