Firefox has some great themes for the computer. I decided to venture out into the unknown and find a theme. Flicking through cats, trees, cars,bodies, Star Wars, Disney, etc I settled on a typical blue sky background with clouds. Not very original. However, when installed, I noticed in the right hand corner “Obrigado Jesus Cristo” – what a nice surprise! It had not been visible on the thumbnail!
Being an Irish Catholic I had to check out the meaning of ‘Obrigado’, just to be sure to be sure. Wiki naturally has all the answers.
It is often suggested that the Japanese word arigatō derives from the Portuguese obrigado, both of which mean “Thank you,” but this is demonstrably false. The Japanese phrase arigatō is a shortened form of arigatō gozaimasu, meaning “Thank you”. This is a form of an adjective, arigatai, for which written records exist dating back to the Man’yōshū, well before Japanese contact with Portugal.[4]
The full derivation is arigatō < arigatau < arigataku < arigatashi < ari + katashi. The medial -k- drops out from -aku- resulting in /au/. This then becomes /oː/ via regular phonological rules. Ari is a verb meaning “to be” and katashi is an adjective meaning “difficult”. The original meaning of “arigatashi” was “difficult to be”, i.e. “rare” and thus “special”. This derivation tries to stem the word to its structural meanings and does not consider the current word’s sentimental development and appreciated meaning.
Superficial appearances notwithstanding, there is absolutely no linguistic relationship to the Portuguese word obrigado of the same meaning.
So I can safely display my new theme, giving it a new meaning of
Special ‘thank you’ Jesus Cristo.
You learn something new every day. Have a good one! 
Very interesting. Thank you!
Thanks Christopher, it was a lovely little surprise. I want to learn a new language. I’m still stuck on Chapter 3 in Italian, But I’m leaning towards Latin. Time to exercise the brain cells during these winter months!
