I have a question for the Japanese forum members.
Do you have trouble pronouncing words like "first", "word", and "bird"?
If you don't, was there a time when you did have trouble pronouncing such words? If so, what did you do to learn to pronounce these sounds better: er, ur, ir?
Here are a couple more examples: heard, third.
I'd appreciate any comments from both teachers and Japanese English language learners, or students, about this particular, though small, pronunciation topic.
Thank you.
