From the description under the video, which is written in Guernesiais, I think it is saying that this video was taken at the Sark Folk Festival in July 2011, and the man in the video is Jan Marquis who is telling us about Guernesiais. From my prior research on Guernesiais, I've found that Jan Marquis is the language development officer on Guernsey since 2008. The position is newly created and gives him the responsibility to promote and preserve the Guernesiais language. In this video, I really enjoy his short lesson on useful Guernsey French expressions for festival goers. Also, I appreciate hearing another person's pronunciation, especially a man's voice, since so far I've only been listening to the one lady's voice on the Learn a Bit of Guernsey French from the BBC website.
Something that struck me right away when viewing this clip was how young this speaker is. Most of what I've read about Guernesiais has mentioned that only the aging elderly are still speaking the language. Seeing this young man speak Guernesiais today is not only uplifting, but it has made the language very relevant in my mind. I didn't know until watching this present-day video that I've been picturing this language as being a bit dusty and brown around the edges. Though, I'm not sure if he's a fluent speaker or a second language learner, but either way hearing him speak Guernesiais makes my heart glow :) I also really enjoy the handpainted posters blowing around him. It looks as though he's had some help from children, perhaps? :D
A la perchoine!
PS Ahaha! I just noticed that there is an English translation under the youtube video description. At least I know I got the gist of it ;) Yay, me.
