Just a thought about the connection between
Faith and
Fay.
In dialects of English,
Fay is an often heard contraction of the word faith. Broad Norfolk and Norwich both pronounce
Faith as
Fay, such as the village of Horsham St
Faith (known simply as St
Fay) and the Norwich road St Faiths
Lane known as
Fay's
Lane.
There is also the East
London expression Iss-fay, meaning so be it or c'est la vie.
