even more significant was that all these Latin words were destined to become the earliest group of borrowings in the future English language which was — much later — built on the basis of the Germanic tribal languages. Which brings us to another epoch, much closer to the English language as we know it, both in geographical and chronological terms.
The fifth century A. D. Several of the Germanic tribes (the most numerous amongst them being the Angles, the Saxons and the Jutes) migrated across the sea now known as the English Channel to the British Isles. There they were confronted by the Celts, the original inhabitants of the Isles. The Celts desperately defended their lands against the invaders, but they were no match for the military-minded Teutons and gradually yielded most of their territory. They retreated to the North and South-West (modern Scotland, Wales and Cornwall). Through their numerous contacts with the defeated Celts, the conquerors got to know and assimilated a number of Celtic words (Mod. E. bald, down, glen, druid, bard, cradle). Especially numerous among the Celtic borrowings were place names, names of rivers, bills, etc. The Germanic tribes occupied the land, but the names of many parts and features of their territory remained Celtic. For instance, the names of the rivers Avon, Exe, Esk, Usk, Ux originate from Celtic words meaning "river" and "water".
Ironically, even the name of the English capital originates from Celtic Llyn + dun in which llyn is another Celtic word for "river" and dun stands for "a fortified hill", the meaning of the whole being "fortress on the hill over the river".
Some Latin words entered the Anglo-Saxon languages through Celtic, among them such widely-used words as street (Lat. strata via) and wall (Lat. vallum).
