Question

New words have been added to English over time _________________.

a.
as a result of innovations in English-speaking countries only
b.
through contact and influence of other cultures and countries
c.
thanks to the Oxford English Dictionary
d.
no new words have been added

Answer 1

Personally, I believe that the answer is C.
Hundreds of new words are added to the dictionary each year, and some of these do not have origins within the English language- therefore, other cultures and countries will have adopted these from their original language.
Hope this helps :)
