weep

To weep is to cry, especially quietly and for a long time. Tears without much noise.

It is a more formal and more literary word than cry, which is why it suits grief and poetry rather than a child in a supermarket. Wounds weep too, meaning they leak fluid, and so do damp walls. The willow is named for it, since a weeping willow hangs down as though grieving. The past tense is wept, and the phrase weep for joy shows the word is not tied only to sorrow.
