Lewis & Short

cumquĕ (quomquĕ or cunquĕ), adv. [cum-que], serves for the generalizing of any action, event, time, etc., however, whenever, howsoever, whensoever, -ever, -soever.

  1. I. Usu. with pronn. and pronom. advv.: quicumque, qualiscumque, etc., ubicumque, quotienscumque, etc.
  2. II. Very rarely standing alone: quae demant cumque dolorem, which remove pain in general, any pain, Lucr. 2, 21: cum solis lumina cumque Inserti fundunt radii per opaca domorum, in whatever manner, id. 2, 114: mihi cumque salve Rite vocanti, Hor. C. 1, 32, 15 (quotiescumque te vocavero, Schol.): aurum cumque a possessore confertur, Cod. Th. 12, 6, 32; cf. Lachm. ad Lucr. vol. 2, p. 288 (who denies the use of cumque except with relatives).
    Note: In Cic. Leg. 3, 3, 9, the reading is most prob. equitatumque qui regat habeto; so B. and K.; v. Orell. N. cr.
