Have you noticed that the word “google” is being used as a verb?
Look at this sentence.
I had no idea what a fun palace was so I googled the expression.
Notice that it is even used with the appropriate tense forms.
But Google is really the name of the search engine of its company Google Inc. It is a trademark. The word describes a brand and the use of the word or brand belongs only to Google Inc.
While Google is still a trademark the word is now commonly used as a part of speech and when it is used everyone understands its meaning. It is now included as a verb in some dictionaries. See how it is defined in the Oxford English Living Dictionary online.
