English is a bit of a mongrel. It is basically a West Germanic language, but contains words from many other languages, especially French, Latin, Greek and Old Norse. In fact, only about 26% of English vocabulary is Germanic, 29% is from French, 29% from Latin, 6% from Greek, and the rest from many other languages [source].
When English borrows words from other languages, which it does all the time, most people see the process as a positive one that expands and enriches English vocabulary.
There will always be some who object to the adoption of certain words, however, within a few generations, or even a few years, those words can become fully integrated in the language, and people might not even be aware they were borrowed in the first place.
Japanese is also open and accepting of foreign words, mainly from Chinese and English. These loan words are changed to fit Japanese phonetics, and some are shortened and combined to make original new words, such as リモコン (rimokon) = remote control, and オープンカー (ōpun-kā) = convertible car.
Borrowing between languages is common around the world where languages come into contact. The borrowing often flows from large languages, like English or Spanish, into smaller languages, such as regional, minority and endangered languages.
When smaller languages borrow from bigger languages, some believe the smaller languages suffer in the process, becoming corrupted, impoverished, polluted, etc. Such sentiments are much less common when talking about borrowing from smaller languages into bigger languages.
There seems to be a double standard here.
Borrowing will happen, even though language regulators, such as the Académie française, might object and try to stop it. Languages change and influence one another. They can borrow many words from other languages without losing their identity, and without breaking down into incomprehensible grunts.
