As a native french speaker, I have the same feeling when reading code written with french keywords, except that since I learned boolean and arithmetic in french, it makes more sense to me to read them in french. As others have pointed out, it seems to only be a matter of how you learn to read and write code.

For comparison, in mathematics I learned to read all the symbols in french, and only learned their english equivalent much later, so it feels uneasy for me when i read their english version. So it is clearly a matter of habit that took its root when you learned reading.
