I've been binging languages lately in attempts to become a polyglot. It's hard to determine how much I'm retaining or not but the word for bread and apple in several languages is pretty obvious. Bread, bröd, ppang, pan, pan, banh, apple, applet, pomme.
I've had to use multiple apps in order to learn more difficult languages. Mandarin Chinese and Korean right now are pretty difficult without visual aid. Korean is harder (for me anyway) than Russian. My pronunciation and handwriting are more atrocious than ever!
