Stratocaster, Sugarcaster...

Worcester is an interesting one- Wicwaraceastre (near enough) is an early version. The Wic bit refers to the Wicca tribe of Anglos Saxons- they gave their name to Wychwood. "wara" just means "inhabitants" or just "people", so the origin is "the chester of the people of the Wicca".

I've often wondered if the Wicca themselves were actually relabelled Britons, because apparently the Gwic- root means "woods" in British, and Wychwood apparently originally covered much of the Midlands, so perhaps the name just means "people of the woods".

And I wonder what was the process by which some became "caster", others "chester" and others still "cester", "cetter" etc., often several forms occurring in the same area.
