I'm digging through Evernote and Diigo to prep for next quarter and came across this map platform again. It mashes together Google Translate with Wikipedia to create something pretty powerful.
(So, you should just go there to click around and discover how it works yourself. But in case you don't have time, I'll explain a bit).
You can type in a word and the platform translates that word into multiple languages and then -- the amazing part -- draws lines between countries of origin for that word and then other countries (mostly colonies) where that word is also used. You can hear the pronunciation of many of the words.
Clicking on the map gives you brief Wikidedia description of the country and a cout of how many other countries speak that same language.
So many layers of learning here.
