The name google was name chosen after Googol (https://it.wikipedia.org/wiki/Googol) to reflect the amount of webpages that in the founder intentions they were about to index.

Apparently when they registered the name the officer/employee was not familiar with the concept and just wrote down the name as they thought it was written: Google.
