List of Celtic place names in Galicia

The Celtic toponymy of Galicia is the whole of the ancient or modern place, river, or mountain names which were originated inside a Celtic language, and thus have Celtic etymology, and which are or were located inside the limits of modern Galicia.

Ancient Celtic toponyms
In Galicia, approximately half of the non Latin toponyms transmitted from antiquity in the works of classical geographers and authors (Pomponius Mela, Pliny the Elder, Ptolemy...), or in epigraphic Roman inscriptions, have been found to be Celtic, being the other half mostly Indo-European but either arguably non Celtic, or lacking a solid Celtic etymology. Here is a non exhaustive list of toponyms which have been found to be, probably, Celtic. The most characteristic element is -bri(s), from Proto-Celtic *brigs, with its derivative *brigā, both meaning 'hill', and thence 'hillfort' and 'town'. The only type of settlement known in Galicia during the Iron Age are forts and fortified towns (castros) built in hills and peninsulas. Many of them were abandoned after the Roman conquest.

Modern and mediaeval toponyms
While there are Celtic toponyms all over Galicia, most Celtic and pre-Latin toponyms can be found along the coastal areas, most notably in the Rías Altas region around A Coruña, and in the valley of the Ulla river.

Regions, Mountains and Islands
Some Galician regions - usually called 'comarcas' when spanning over several municipalities, or concellos (councils) otherwise - maintain names either directly inherited from pre-Roman tribal and sub-tribal names, or simply with pre-Roman origin:


 * Arousa (Arauza, 899 CE): Island and municipality in Arousa bay, Pontevedra. Probably Celtic, to *(p)are-auso- 'cheek'.
 * Bergantiños (Bregantinos, 924): Region, to *brigantīno- 'king', or to *brigantigno-, both etymons would have yielded the same result. Cf. Middle Welsh brenhin 'king'.
 * Carnota (Carnota, 915 AD): Coastal council and ancient territory, it is presided by the Monte do Pindo, an anciently sacred granite mountain. It was also the name of a mountain near Doroña, Vilarmaior. To *karn- 'pile, heap', with a hypocoristic suffix.
 * Céltigos (Celticos in 569): Region, to the local tribe of the Celtici (plural accusative Celticos), who inhabited the westernmost regions of Galicia. For the *kelt- element, see the article on the names of the Celts. With the same origin, and implying further migrations:
 * Céltigos, a village, in Sarria.
 * Céltigos, a parish, in Frades.
 * Céltigos, a parish, in Ortigueira.


 * Cervantes: Mountainous country and municipality in eastern Galicia. To *kerbo- 'pointed, sharp'.

 * Larouco (Latin Larauco): A 1400-metre-high mountain, in Baltar; also a municipality and a parish by the Sil river; there is also a village under the name Larouce, in O Carballiño. Probably from *(p)lārHw-ko-, a derivative of 'plain/field'. Cf. Old Irish lár 'ground, surface, middle'.
 * Lemos (Lemabus, 841 CE): A large valley, south of Lugo. Its name is an evolution of the name of the Lemavi people, who inhabited these lands. To Celtic *lēmo- 'elm'.
 * Nendos (Nemitos, 842): Region and ancient territory, to Celtic *nemeto- 'sacred place, sanctuary', and 'privileged person'.
 * Tambo (Tanao, 911): Small island in Pontevedra bay, to Celtic *tanawos 'thin'. Cf. Breton tanaw, idem.

Rivers
Many Galician rivers preserve old Celtic and pre-Roman Indo-European names, most notably larger ones. Others have lost its pre-Latin name, but its old namewas recorded in Medieval scriptures:


 * Ambía (Ambia, 949 CE): A tributary to the Arnoia. To Proto-Celtic *ambe- 'river'.
 * Barbanza: A short mountain river in A Coruña province, to *bhr̥u̯-n̥ti̯-ah2‑ 'boiling > waterfall'.

To Celtic *dēwā 'goddess'. There is also a small village called Deva in Cervantes, Lugo. Cf. also rivers Deva in Asturias and river Dee, Wales, ancient Dēva.
 * Dubra (Dubria, 1110 CE), affluent of the Tambre River. From Proto-Celtic *dubrā- 'dark', which in several Celtic languages developed semantically into the substantive 'water'. The municipality of Val do Dubra ('Dubra's Valley') receives its name from this river. Compare with the Asturian Dobra, and the rivers Douvres in France and Dover in England.
 * Landro:. River which flows through the town of Viveiro into the Bay of Biscay. To *(p)lān- '?River of the plane', or to *land- 'open land (valley)'.
 * Limia: To Celtic *līmā- 'flood', so probably 'The river of the flooded area'. In the past it formed a large swampy area near its sources which was mostly desiccated during the 20th century.

 * Mendo (Minuete, 964 CE): A river which flows thought Betanzos into the sea, together with the larger Mandeo. To *menwo- 'small, minute', 'Minor River'. Cf. Irish menb 'idem'.
 * Miño or Minho: Largest river in Galicia, to *mīno- 'tender, soft'. Cf. Old Irish mín idem.
 * Nanton, river, tributary of the Tambre, from Proto-Celtic *nanto- 'stream, valley'. Another different one, the Río das Gándaras also bore the same name in the past (Nantoni, 955 CE).
 * Navia: Large river which marked the frontier of Galicia and Asturias during the first centuries of the common era. It flows thought a canyon for much of its course. To *nāwiā- 'boat (vase, bowl)'. Cf Spanish nava 'valley in between mountains'. Another river, a tributary of the Sil river born by the 1700 meters high mountains of Serra de Queixa, in the province of Ourense, is also named Navea.




 * Samo: A tributary of the Tambre. To Celtic *sāmo- 'calm, easy, pleasant'. Cf. Middle Irish sám 'idem'.
 * Tambre: Ancient Tamaris. To *tamo- 'dark', so 'Dark river'. Cf. the British rivers Tamar (ancient Tamarus), Thames (Tamesis) and Tamius. Another two Galician rivers bear closely related names (both to *Tam-ikā): Tâmega (Tamice, 982): Tributary of the Douro; and Támoga or Támboga (Tamega, 934 CE): Tributary of the Miño.
 * Rio de Perros (Vernesga, 1078 CE), sub-tributary of the Miño: To *wernes-ikā, to *werno- 'alder, alder-tree'.
 * Río Grande, a tributary of the Eo river, was attested as Alesantia in 775: To *Alisantiā as, for example, the rivers Elsenz, Auzance, Alrance in Germany and France. The old name is preserved in the name of a village As Anzas. Related: Esgos, a municipality in Ourense, from Alesgos (ancient names of the local river), from *Alisikos.

Parishes and Villages
Most of the 3794 parishes, small rural districts, of Galicia continue medieval and Roman villas, frequently founded near, or even on top, of old Iron Age hillforts. Many of these parishes preserve old pre-Latin names.

Composites containing Celtic *-brig- 'hill'
The most frequent element among the Celtic toponyms of Galicia is *brigs, meaning 'hill, high place', and by extension 'hillfort'. Usually it is the second element in composite toponyms ending in -bre, -be or -ve, being cognate of Irish Gaelic brí 'hill', with the same origin: Proto-Celtic *-brigs > -brixs > -bris. A few toponyms ending in -bra proceed from a derivative -brigā 'hill(fort)', which also originated Breton and Welsh languages bre 'hill'. Some of these toponyms are:
