In this scenario, regional patois/dialects/languages of England are as strong in 1800 in rural as the French regions as in France/Germany in the 19th century. Everywhere rural speaks one of the following dialects/languages:
*Kentish
*Sussexish
*Wessexish
*Cornish (celtic)
*Middlesexish
*Merkish (Mercian)
*EastEnglish (East Anglian)
*East-Middish (East midlands)
*Northumbrish (Northumbrian with varieties, this being most distinct from Standard English)
All of these (except for Cornish)would be more Germanic than standard English (eg: use Wick/by for village and Dale for valley etc). Have standard English have the same status as French in France at this time.
Questions:
When would 'Centralisation' occur, before or after 1900?
How would this situation affect English attitudes towards non-English languages meaning Irish, Gaelic, Welsh and Cornish (which doesn't disappear before 1800)
How would English be different today in terms of status?
How would English spoken natively outside England be different?
