Word origins
A computerised survey of about 80,000 words in the old Shorter Oxford Dictionary (3rd ed.) was published in Ordered Profusion by Thomas Finkenstaedt and Dieter Wolff (1973)[1] that estimated the origin of English words as follows:
Influences in English vocabulary
Langue d'oïl, including French and Old Norman: 28.3%
Latin, including modern scientific and technical Latin: 28.24%
Germanic languages – inherited from Old English, from Proto-Germanic, or a more recent borrowing from a Germanic language such as Old Norse; does not include Germanic words borrowed from a Romance language, i.e., coming from the Germanic element in French, Latin or other Romance languages: 25%
Greek: 5.32%
No etymology given: 4.03%
Derived from proper names: 3.28%
All other languages: less than 1%
A survey by Joseph M. Williams in Origins of the English Language of 10,000 words taken from several thousand business letters gave this set of statistics:[2]
French (langue d'oïl): 41%
"Native" English: 33%
Latin: 15%
Old Norse: 5%
Dutch: 1%
