The June 6 letter Languages essential says that multilingual foreigners say that a person who speaks three languages is trilingual; two languages, bilingual; and one language is an American. I would add that in Miami, the one language spoken is Spanish.
I have lost count of the number of times that I have been in a place of business and the employees working there either speak no English or so little that they cannot be understood. I don’t agree that in America we must speak English only, but bilingualism means you speak two languages fluently.
It works both ways.
