I'm acknowledged across the UK as a pretty experienced expert on Klingon, and I have frankly tried making Klingon accessible to the general population for more than twenty years, now. And with Star Trek Into Darkness (poH mIgh 'el Hov leng) in the cinemas right now, this seems as good a time as any.
I began with the introductory post nuqneH. This said a little about the blog, and what it aims to do.
It was followed by this post, showing fifty highly useful Klingon nouns. A basic vocabulary which you can access regularly while learning the words off by heart.
So, then, tlhIngan paQDI'norgh is a go as of 2013 05 20. I hope you will stick with it, and learn enough Klingon to amaze and astonish your friends. Qapla'!
