I took 3 years of Japanese in high school and have now been out for about a year and a halfish. Without a native speaker around to converse with, I find that when it comes to pronouncing る, especially when it is the second syllable in a word, I have great difficulty.
I'm not sure why, but れ and る have become a real challenge for me to pronounce correctly. I tend to want to pronounce them by kind of smacking the tip of my tongue against the roof of my mouth--as when when rolls one's "r"s. It has become impossible for me to say, for example, とまれ quickly.
I've heard that the r/l sound in Japanese is made as if one were pronouncing a d without touching the roof of one's mouth...easier said than done though...Any tips?
Pictures of "correct" tongue placement would prob. be helpful...
