A map's way of pointing out directions without being pointed about it.

means The star-shaped diagram on a map or chart that marks the cardinal and intercardinal directions, so you know which way north actually is.

from 'Compass' traces back through French and Latin to 'compassare' — to measure out, to pace off evenly — the same root that gives us 'pace' and sits behind words of careful measurement. 'Rose' is the visual half of the story: early chartmakers drew the direction points radiating from a center like petals, and the many-pointed starburst simply looked like a flower. The design dates to the great age of sea charts, when points for the main winds (and the directions between them) fanned out from a circle so sailors could lay a course at a glance — practical geometry that earned itself a pretty name.
