One of my biggest pet peeves is the spelling of the Colombia. In fact, I have even seen news programs get it wrong. The country of Colombia does not have a “U” in it. Not even in the “English version”. In Spanish AND English the country has two O’s. No U’s. This is one fact my students know not to mess up.
There are tons of companies that use the spelling “Columbia”. Columbia Sportswear is probably the biggest one. The New York university Columbia is well know, along with other colleges going by that name. Among cities named Columbia, we must mention the capital of South Carolina.
