The website Banque de dépannage linguistique (BDL) will have a lot of useful resources if you're interested! For instance, how to write a professional sounding email, names of official documents, invoice templates.
Highlights (good and bad):
* emails -> courriels (courrier + iels; mail + similar sounding syllable)*
* spam mail -> pourriels (pourri + iels; rotten + similar lexem as courriels)
* to spoil (as in spoilers) -> divulgâcher (divulguer + gâcher; to reveal + to ruin)
* to mansplain -> mecspliquer (mec + expliquer; man + to explain); This one is outrageous (and uncommon) because it's an homonym to "m'expliquer" (explain to me)
* to browse (the web) -> naviguer (as in "to navigate"; browser -> "navigateur")
I’m old enough to remember when it was called web surfing and everyone used Netscape Navigator.
