shah that has to do with the previous french influence. During the ottoman rule, the french were the protectors of maronites and founded most schools and universities and missions in Lebanon, and taught the french language.
Then in 1918, lebanon became part of the french mandate. Our constitution and laws copy the french laws in many paragraphs and ways.
Even now most good schools teach in french and most are french schools, at least in christians areas. The rest are mostly english.
Even public schools in most areas teach biology, maths, etc... in french.
When i was young i was taught everything in French.
When ethan posted the elephant joke i didnt get it because we use the word "elephant" in french for the animal
we say "merci" for thank you, bonjour, etc... and actually never use the arab versions.
But even if for some idiots its a status symbol, for most its just the way they were taught in schools and universities.
