is the correct way to pronounce the letter 'r' in french with the back of your throat? like hocking up a loogie but not as intense. i dont know how to spell out the sound. so in this case with garçon and propre, there is no actual r sound, but instead its that sound from the back of your throat. is this right?
It is extremely Parisian to do the glottal r, though it is common enough that most people will teach you to do it that way. The farther you get from Paris, the more people simply roll their r's.
In Hebrew, the letters chet and chaf also give you that sound. German and Yiddish also have that sound, it's not French-exclusive.
lol! I wonder if it is used in the same context in french or if there is some other word/expression for being clean in that way.
Interestingly enough, the French word for clean off drugs would be "clean". You could say, "Je suis clean depuis un an." Meaning, "I have been clean for a year." It is probably derived from the English language.
