a pool, a lake, sometimes applied to a waterfall, not as associated with the cascade, but with the pool into which it is received, as in the Linn of Dee, in Aberdeenshire, and Corra-linn, on the Clyde. Dublin (the black pool) takes its name from that part of the R. Liffey on which it is built; and there are several other places in Ireland whose names have the same meaning, although variously spelt, as Devlin, in Mayo; Dowling and Doolin, in Kilkenny and Clare; Ballinadoolin (the town of the black pool), in Kildare. In several such cases the proper name was _Ath-cliath_ (hurdle ford), literally _Baile-atha-cliath_ (the town of the hurdle ford), the original name of Dublin. The ancient name of Lincoln, _Lindum_, is the hill fort on the pool; Linlithgow comes from the same root, and is probably the gray lake--how it came by the termination _gow_, _gu_, or _cu_, as it is variously spelt, cannot be determined; Linton, in Roxburghshire, is the town on the pool; Linton, in Peebles, on the R. Lyne--in Cambridge (on the brook, _hlynna_); Dupplin, on the R. Earn, in Perthshire (the black pool); Crailing, in Berwickshire, anc. _Traverlin_ (the dwellings, _treabhar_, on the pool); Edarline (between the pools); Aber-glas-lyn (the estuary of the blue pool), in Wales; Lynn-Regis (the king’s pool), in Norfolk; Roslin (the projecting point on the pool), in Mid Lothian; Lynn-yr-Afrange (the beaver’s pool), in Wales; Mauchline, in Ayrshire (the pool in the plain, _magh_); Lincluden, in Kirkcudbright (the pool of the R. Cluden); Lindores, in Fife, probably not from this root, but a corrupt. of _Lann-Tours_, being the seat of the abbey of Tours, founded by David, Earl of Huntingdon. Lyme-Regis (the king’s pool), in Dorset; Lymington, anc. _Linton_ (the town on the pool), in Hants; Llyn-hir (long pool); Llyn-y-cun (the dog’s pool), in Carnarvon; Llynn-y-Nadroedd (the adder’s pool); Llynn-ye-cae (the enclosed pool), all in Wales; Llyn-tegid (the fair or beautiful lake); Lly-gwyn, with the same meaning; Llyn-Teivy, of the R. Teivy, in Wales; Llyn-Safaddon, corrupt. from _Llyn-saf-baddon_ (the standing pool or fixed bathing place)--_v._ BAD. [Sidenote: LIOS, or LIS (Gadhelic), LES (Breton and Cornish),]
