Often _ceaster_, from _castrum_, was added: Gwent, Venta Belgarum, Wintan-ceaster, Winteceaster, Winchester; Isca, Exan-ceaster, Execestre, Exeter; Corinium, Cyren-ceaster, Cirencester.

Almost every place which is known to have had a name at the English Conquest retained that name afterwards, in a more or less clipped or altered form.
Examples are Kent, Wight, Devon, Dorset; Manchester, Lancaster, Doncaster, Leicester, Gloucester, Worcester, Colchester, Silchester, Uttoxeter, Wroxeter, and Chester; Thames, Severn, Ouse, Don, Aire, Derwent, Swale, and Tyne.

Even where the Roman name is now lost, as at Pevensey, the old form was retained in Early English days; for the "Chronicle" calls it Andredes-ceaster, that is to say, Anderida.

So the old name of Bath is Akemannes-ceaster, derived from the Latin _Aqua_, Cissan-ceaster, Chichester, forms an almost solitary exception.
Canterbury, or Cant-wara-byrig, was correctly known as Dwrovernum or Doroberna in Latin documents of the Anglo-Saxon period.
On the other hand, the true English towns which grew up around the strictly English settlements, bore names of three sorts.

The first were the clan villages, the _hams_ or _tuns_, such as Baenesingatun, Bensington; Snotingaham, Nottingham; Glaestingabyrig, Glastonbury; and Waeringwica, Warwick.
