Necessary. Mother: What, are you busy, ho? Need you my help? Juliet: No, madam; we have culled such necessaries / As are behoveful for our state tomorrow. / So please you, let me now be left alone, / And let the nurse this night sit up with you; / For I am sure you have your hands full all / In this so sudden business. From Shakespeare's Romeo and Juliet (Act IV, Scene 3).
