Learning a new language (and culture) is both fun, and sometimes, funny. The general assumption about Spanish is that you can put an “o” on the end of the wordo (see, like that) and that this “o” will make it Spanish. Lots of the words are the indeed the same or similar in English and Spanish. These are called cognates. An example is dictionary: diccionario. Looks the same, must be the same. But, how easily one can land, mouth on foot! Here are some other words and phrases that can make for sticky or embarrassing situations (does my quick doodle better illustrate the point?).
Also, today is “martes trece” or “Tuesday the 13th” which is the equivalent to “Friday the Thirteenth” — a day of bad luck, a day not to leave your house, not to start a new business, etc. in Spanish-speaking countries. Perhaps a day to stay indoors looking up funny cognates online. I am taking note of these as I go along, so if I get them wrong, please comment! I look forward to trying to avoid too many encounters of foot in mouth once I get to Colombia.
