This is a common element in Montgomeryshire place names, = raised ground, hump, hill. CWM CAE Brook: SO 2793 Camlad L. Coom Cay Brook is noted in the Perambulation of Churchstoke, 1702. (Mont. Coll.

Cwm Cidyn L. = of the black-stone cwm. n CWM CIDYN: SN 9290 Trannon R. v. n. Tan Lan. Cwm Ciden appears on Enc. M. of Esceireth Township, 1826. Cidyn is dialect form of cudyn = lock of hair, whisp, tuft of grass, refering perhaps to meagre pasture rather than to the smallness of the stream. n. CWM CIGNANT: SO 0182 --). Feinion R. Probably the Teinion in S.E.'s list. Cwm Cignant shown at SO 1196. Does this name start with a nant called cig (meat) after which a cwm was named, with the cwm giving its name later to the stream? n. CWM COCH: SN 921847 Severn R. = of the red cwm. n. CWM CWTA: SN 9892 Colwyn R. There is a hab. of this name. = of the short cwm. n. CWM DWYGO: SJ 0425 Tanat R. On OS 1826 Cwm Dwygo is named while the stream is shown without a name. V. Angell. Both E.A. and M.E. regard Dwygo as a pers. n. n. CWM DYFNANT: SJ 0116 Efyrnwy R. S.E. Dyfnant. Nearby are Dyfnant, hab., and Maes Dyfnant. Which meaning has nant in Dyfnant? Cf. n. Cwm Cignant. = of the cwm of the deep stream or valley. CWMFFRWD Brook: SO 0288 Severn R. Named after cwm or hab. of this name. = brook cwm (brook) n. CWM FFYNNON: SJ 0928 Rhaeadr L. = of the cwm of a well. n. CWM GERWYN: SN 9895 a. Garno L. Nearby are Blaen Cwm y Gerwyn and Cwm Gerwyn. M.E. cites "a little brook called kerwyn" from a 1609 document and Nanty Cerwyny from a 16th century document. These forms suggest that the stream was once called nant Cerwyn or nant y Cerwynni and that the Cwm was named after the stream. The last stage was for the stream to be named after the cwm. Cerwyn is a fern. noun = vat, cask; if this is the meaning it can be added to the list of names of the container type. Two other derivations should be considered. The original form may have been gerwin (= harsh, inclement) + -i. It could also have been the gerwyn which occurs in cerwynllys, y gerwynllys, llysiau'r gerwyn, = ground ivy. (Incidentally vats and ground ivy are associated with brewing!) n. CWM GWAIR: SN 8589 Biga R. Mentioned in P.H. Trefeglwys (M.C., XII, 11). On Enc.
