ugh i hate having trouble with Spanish...
I hate not being able to roll my R's. Is there a way to learn how to do that???
There's lots of youtubes, usually under "trill R" rather than rolled R, as that often get's you the french one too.
I don't have a specific recommendation as I'm still learning. I've heard it can take quite a while, so I guess the main thing is just to take the pressure off yourself and practice whichever technique feels comfortable to you?
