one, the adjective byr, fern. ber, appears to be an acceptable derivation. Cf Nant Cwta and Hirnant. = short stream. BYS: Probably SO 0080 Cydros R. T.M. Llandinam. 1847 has Cwmbus located SO 0080. M.R., 341, 1580 document cites "a little stream called Bys" in the township of Dethenydd in the parish of Llandinam, also mentioning "a little stream called Gwrach a certain water called Gywynion and a small steam called Avon (blank)," the blank being a hole in the document. Dethenydd is a township, (SO 0283) v. Gwrach and Gywynion. BYTHERIG: SJ 2814 Severn R. E.A. quotes Bytherick in Arch. Cam., 1839, 89, where it is explained as from "by the rick." Varegrek in a 1292 doc. may be the township of Bytherick. (Mont. Coll. LXIX, 40). E.A. tentatively suggests < byth (always, for ever, cf. Bythigion). E.A. has further suggestions < byddar, (deaf) and < bythair (belch). The latter would be descriptive of the sound of the stream. BYTHIGION: SN 8882 a stream probably called Briwnant (v.) forming a tributary Bronfelen Brook, R. SN 8983. Bythigion is mentioned in P.H. Llangurig (Mont. Coll. 111, 280) Blaen Bythigion is named SN 8882. E.A. derives < byth- (of Bytherig), denoting a continuous flow of water, the opposite of streams which are sometimes dry, e.g. Hafhesp. CADNANT: SJ 1518 Cain R. GPC cad = (1) battle, (2) hare. If the first, cf. Aeron. n. y CAE: SJ 060037^ Rhiw (N) L. Two habs, Nant y Cae Ucha and Isa, are named on Sheet SJ 00 but not the stream. = of the field. CAEBITRACH, CAEBITRA: SO 2794 Camlad L. S.E. has Cae Butraf or Cae Butrach; M.E. Caebitra and Ceibitra; Caebitra on OS 1836. M.E.'s explanation is cae (field) + compara- tive of budr (dirty, filthy). The ending may however not indicate a comparative but an intensification of the pejorative meaning of budr. n. CAE DDOLE: Marked on Enc. M. ofDwyrhiw 1795/6. In the Cedewain Enclosure Report of 1818 (map xxiii, reference provided by Mr D. W. Smith) the spelling is Nant Cyddole. Hab. Cae'r Ddol is shown on SJ 0803. The tautology in Cae'r Ddol/Ddolau (the field of the meadow(s) suggests that this was not the original form. The form Cyddole may be the earlier form < cy(d) + dolau, cyd being the same element as in n. Cytir (v.) and Cytgae (=common boundary) and several other combinations with cyd- (v. GPC). If so, = of the common (or border) meadows. It has the same water course as Nant Wtre Wen (v.). n. CAEGARW: SN 9680 Dulas R. Hab, Caegarw shown SN 9679. = of the rough field. n. CAE LEDAN: v. Cledan. CAERAU Brook: SN 9985 Severn R. So named locally after hab. (= walls, forts). Also known as Bradnant and Nant y Filltir. n. CAERGWEISION: SH 9713 Twrch L. Hab. Cae'r Gweision is nearby. Gwas, pi gweision, = young man, is used for male farm workers. n. y CAETHLE: SH 9714 Twrch R. < caeth (confined, restricted) + lie (place). It could mean a prison but is more likely to refer to the stubborn nature of the land for farming. But v. Cathau. CAFNANT/N. CAFNANT: SJ 105065 Banw R. Nant y Bwt (v.) joins it. Both streams are shown on map of 19th century Llanfair Caereinion. (Mont. Coll LXVII. 56). These streams are now culverted. Probably from cafn + nant. Cafn = trough, also millrace. As the two streams fed
