The kanji 久 is an ideogrammic compound. It combines two elements: a radical meaning "person," and a component that represents a "crooked leg." Initially, the shape of 久 resembled a person with a bent knee, representing someone who is kneeling for a long time. This is related to the idea of "long duration" or "lasting." Over time, the form of the character has changed to what we see today. The meaning expanded from the physical posture to the concept of lasting for a long time.
