There were a few questions that I had a hard time answering...one example: I may use several words for a semi truck, sometimes I call it a tractor-trailer, sometimes an 18 wheeler...
Interesting test
I was born in upstate NY, moved to CA when I was 4, then AZ for the last 20 years before coming to TV a year ago. The test put me in San Francisco or St Lake City.
I'm sure many of the words we individually use are influenced by what our parents called things, as well as local words/pronunciations.
