a hollow, cognate with the Lat. _lacus_ and the Grk. _lakkos_; _e.g._ Logie (the hollow), in Stirling; Logiealmond (the hollow of the R. Almond in Perth); Logie-Buchan, in Aberdeenshire; Logie-Coldstone, Gael. _Lag-cul-duine_ (the hollow behind the fort), Aberdeen; Logie-Easter and Logie-Wester, in Cromarty; Logie Loch and Laggan Loch (the lake in the hollow); Logan (the little hollow); Logierait, Gael. _Lag-an-rath_ (the hollow of the _rath_ or castle, so called from the Earls of Atholl having formerly had their castle there in Perthshire); Mortlach, Co. Banff, probably meaning the great hollow. In Ireland: Legachory, Lagacurry, Legacurry (the hollow of the pit or caldron, _coire_); Lugduff (dark hollow); Lugnaquillia (the highest of the Wicklow mountains), is from the Irish _Lug-na-gcoilleach_ (the hollow of the cocks, _i.e._ _grouse_); Lough Logan (the lake of the little hollow); Lagnieu, in France, anc. _Lagniacum_ (the place in the hollow of the waters); Laconia and Lacedemonia (in the hollow), in Greece. [Sidenote: LANN (Gadhelic), LLAN (Cym.-Cel.), LAND (Teut.),] an enclosure, a church, a house; but Mr. Skene considers that the Cel. _llan_ comes from the Lat. _planum_ (a level place), just as the Gael. _lan_ (full) comes from the Lat. _plenus_. This word is more common in Welsh names than in the topography of Ireland and Scotland, and in its signification of a church forms the groundwork of a vast number of Welsh names. In Ireland it means a house as well as a church, as in Landbrock (the badger’s house); Landmore (the great church), in Londonderry; Landahussy (O’Hussy’s church), in Tyrone; Lanaglug (the church of the bells). It is not so frequent in Scotland, but the modern name of Lamlash, in the Island of Arran, formerly _Ard-na-Molas_, the height of St. Molios, who lived in a cave there, seems to be the church or enclosure of this saint; Lambride, in Forfar, is _Lannbride_ (St. Bridget’s church); Lumphanan is from _Lann-Finan_ (St. Finan’s church). The derivation of Lanark, anc. _Lanerk_, is probably from the Welsh _Llanerch_ (a distinct spot or fertile piece of ground). There are many examples of this root in Brittany; _e.g._ Lanleff (the enclosure on the R. Leff); Lanmeur (great church); Lannion (the little enclosure); Landerneau and Lannoy (the enclosure on the water); but in French topography the Teut. _land_ generally signifies uncultivated ground; _e.g._ La Lande, Landes, Landelles, La Landelle, Les Landais, Landau, etc.--_v._ Cocheris’s _Noms de Lieu_. Launceston, in Cornwall, is probably corrupt. from _Llan-Stephen_. The greatest number of our examples must be taken from Wales. There are Lantony or _Llan-Ddevinant_ (the church of St. David in the valley, _nant_, of the R. Hodeny); Llan-Dewi-Aberarth (St. David’s church at the mouth of the Arth); Lampeter (of St. Peter); Llan-Asaph (of St. Asaph); Llanbadern-fawr (the great church founded by Paternus), also
