Manchester
The name Manchester originates from the Latin name "Mamucium" or its variant "Mancunium" and the citizens are still referred to as Mancunians (). These are generally thought to represent a Latinisation of an original Brittonic name, either from "mamm-" ("breast", in reference to a "breast-like hill") or from "mamma" ("mother", in reference to a local river goddess). Both meanings are preserved in Insular Celtic languages, such as "mam" meaning "breast" in Irish and "mother" in Welsh. The suffix -chester is a survival of Old English "ceaster" and from that "castra" in latin for camp or settlement ("fort; fortified town").
