means Crying; shedding tears, often quietly or continuously, from grief, pain, or strong feeling — and by extension, anything that drips or oozes liquid, like a weeping wound or a weeping willow.

from From Old English 'wepan,' to weep, which is thought to be imitative in origin — an echo of the sound of wailing itself, so the word may literally be the noise of crying turned into language. It has cousins across the old Germanic tongues. The drooping willow earned its name by visual metaphor, its trailing branches looking like a figure bowed in grief, as if the tree itself were shedding tears.
