Expressed sorrow, regret, or sadness about something; mourned or grieved deeply.
From Latin 'lamentari' (to wail). Related to 'lament' (a cry of grief). The word came into Middle English from French and has maintained its sense of deep sorrow since the 12th century.
Lamentations is actually an entire book of the Bible where the prophet Jeremiah 'laments' the destruction of Jerusalem—it's one of the few books in the Bible written entirely as a song of grief, showing how important mourning rituals were in ancient cultures!
