If you want to challenge yourself to a very fun podcast: ゆる言語学ラジオ - 単語はすごい

I love this podcast. They discuss a lot of the more mind-blowing quirks of language from a Japanese perspective. It has led to some truly mind-blowing moments for me, where I have understood English from a completely new perspective, and I really enjoy it.

The catch is that it gets pretty hard at times! But if you want to discuss it here, that could be pretty fun! This episode was particularly interesting.

For some additional context: they're discussing how amazing "vocabulary" is, and they start the podcast joking around a bit before getting into the subject matter. Hope some of our most daring members give it a try!
