To mourn is to feel or express sadness or distress because of some loss, affliction, or misfortune; mourning is thought of as prolonged, grief or regret may be transient. One may grieve or mourn, regret, rue, or sorrow without a sound; he bemoans with suppressed and often inarticulate sounds of grief; he bewails with passionate utterance, whether of inarticulate cries or of spoken words. He laments in plaintive or pathetic words, as the prophet Jeremiah in his "Lamentations." One deplores with settled sorrow which may or may not find relief in words. One is made to rue an act by some misfortune resulting, or by some penalty or vengeance inflicted because of it. One regrets a slight misfortune or a hasty word; he sorrows over the death of a friend.
