Heh! So many 'I like languages' people...
Good ideia, Mr3d! It is a start. If you visit
this page, and search, you'll find lots of HP terms in other languages... But we could have a list of our own...
The ser/estar thing also occurs in Portuguese. 'Ser' is to permanent states (like, I'm your son; You are a girl; ...) and 'estar' is to temporary ones (I'm here; I'm sad; You're beautiful, today; ...)
Thoughts/Words:
About thoughts that are not composed of words, like, when you remeber the taste of something, or the landscape you've seen, or the sound of 'Für Elise', ..., they can't be compared to words, I guess.
About the others, like when you are talking to someone and suddenly remeber one thing you'd like to tell, I think the thought comes first. For one hand, a thought is not a 'human made' thing. It's inherent (sp). Because the Human Race is considered inteligent, it may have thoughts. But words were made to transmit these thoughts, so, my guess is that thoughts come always first...
