How to term those words which are not by default English but are added over time?
Consider for example Google. Is it an English word now? Or is it just a usage?
Answer
Use of the word “google” to mean “perform an Internet-based search (for)” is an example of genericization.
Wikipedia has a list of terms that have entered the language this way. Some may surprise you.
Wikipedia also has a helpful page on the topic, which includes commentary on the phenomenon itself.
If you’re looking for a more general term that covers words entering the language that are not necessarily trademarks, I recommend neologism.
