Learning Japanese in a home with three native speakers, I expect them to laugh at me a lot, as I make a lot of mistakes.  A LOT of mistakes…sometimes they are practically rolling on the floor, and between catching thier breath and the next bout of giggles, they correct me.

But this evening something different came up. Apparently my pronunciation of ら, り, る and れ is incorrect but ろ is ok. It doesn’t seem to matter how I place my tongue in my mouth, it comes out the same way.

I can’t tell the difference in how they say it, compared to how I say it, but all three of them were trying to get me to pronounce it right, without success.

Any tips on what I might be doing wrong or how to correct it?
