(According to Mr Durkin English contains around 13,000 words with Latin roots.
The next most influential language is French with 6,000 words. (Borrowed - not stolen +Xeb eke .)
In fact, according to Mr Durkin's research, Hawaiian, Turkish, Zulu and Swahili have had more of an impact than Welsh and Cornish.
Welsh ranked 30th.
Cornish came in at 45th place.
Even the word pasty came from France and not Cornwall.)
