From the Radaro Team

 It’s the day after Valentines Day, we hope you were able to spend it with those you love! If not, let Esperanto be your lover and let it fill the gaping void in your heart with its core values. Esperanto can’t leave you, even though Suzy did… it’s not too late Suzy… I can change…

This week on Radaro, we have some important news, new EsperantoGramatiko, Donato’s Diamonds, website of the week, the latest addition to our Creations of the Esperantujo section, and an experimental section by one of Radaro’s editors, Quintyn!

Website of the Week: Esperanto USA

It’s been a while since we’ve featured Esperanto USA in any direct way, but there are always new komencantoj joining the community so it’s good to know about North America’s largest Esperanto organization. Here you can find news and updates about Esperanto at the national level such as publications, club meetings, fundraisers, and other activities. They also have an online store where you can pick up Esperanto-based merch like buttons, books, music, and a variety of other items!

Donato’s Diamonds: Geografio en Esperanto!

Learn about specific regions of the world in greater detail through Esperanto with these detailed maps! This link will take you to a page where you can scroll through a variety of world and regional maps that not only include country names, but also of towns, cities, and languages. One of my favorites is a map of the eatern Mediterreanean during the Middle Ages, it’s that detailed and in Esperanto!


Vikipedio Article of the Week

Came across a rather detailed article about the statistics of Esperantujo (speakers, denaskuloj, books, and so on). Since Esperanto is not a national language, the number of speakers is obscure compared to English and other major languages. Therefore, having an article exclusively on the topic should be informative to any learners wanting to know about the size of Esperantujo. Think of it as a sort of unofficial census record of Esperanto speakers!

Pensoj de Q


This is an experimental section of the newsletter where I, Quintyn, world-renowned editor, discuss an Esperanto related topic. For this edition, it covers the use of the word in Esperanto “Jen”.  For those of you who don’t know, this word corresponds roughly to the English “Here’s____” or “This is ____” or if you want to get old-timey, “Behold!”. It’s a handy word that cuts down on the amount of time one has to spend saying some form of the word “esti” when speaking Esperanto. Instead of saying “Tiu estas Chuck” when introducing someone, you can say “Jen, Chuck”. Or you’re throwing a pen to a friend who just requested it “Jen mia plumo” instead of  “Tio estas mia plumo”.

I do appreciate having a word that’s so handy in a language that doesn’t use contractions and often has a way of being a bit longer than its English counterpart. It’s not just Esperanto that does this, so do other languages like Italian’s “Ecco” from Latin’s “Ecce” (for those of you who study Latin in high school, the name of a popular textbook, “Ecce Romani” literally means “Behold, Romans!”). While words in English which once served a similar function, such as “Behold!” (I feel that always including an exclamation mark after this word is necessary) or “Lo!”, are becoming obsolete, I urge the readers of this website to try to use such words more in their everyday speech, both in English and Esperanto. Save the brute awesomeness of “Behold!” and “Lo!” and coax its existence back into minds of the English lexicon. And don’t let English’s habit of dropping handy words like these cause you to make lesser use of “jen” in Esperanto.
