msseeker, there is almost nothing in your message that is right and I see not much point in spending all the space here in correcting everything other than to say you clearly never studied the French language.
As to English, by the way, please note the following from Merriam-Webster:
Origin of Nonchalant
French, from Old French, from present participle of nonchaloir to disregard, from non- + chaloir to concern, from Latin cal?re to be warm. . .
That would make you wrong in two languages.
