Characters that sound alike... How do I determine which one to use?
ㅐ, ㅒ, ㅔ, ㅖ. ㅝ , ㅞ , ㅟ .
Group 1 sound all alike, as well group 2 sound alike. So how do I know which one to use??
Thank you,
Chris.

Hellow, Chris!

As the native speakers say, you just have to memorize the writing of words with such letters since it sounds the same.

By the way, there are really have a logically based choosing which letter needs to use. But it is not rules, it is etymology researches. Only professional Korean philologists really knows what exactly goes on there.

Check out lectures by the awesome Korean native teacher:
ㅐ, ㅒ, ㅔ, ㅖ youtube.com/watch?v=jwqzU2R...
ㅘ, ㅙ, ㅚ, ㅝ, ㅞ, ㅟ youtube.com/watch?v=mKUT8_E...

Thank you Nicko for your reply. I think my still lifetime won't be enough to master such complexity. I'm next month becoming 70 years. Take care, Chris.

It is not complexity, but require some kind of challenging inspiration. Scientists have proved that regular exercise for six months, coupled with proper nutrition, can stop brain aging and even reverse this process: https://www.health.harvard....

Also I would recommend you to read some tips from Kato Lomb (famous polyglot), Steve Kaufmann (co-founder of LingQ) and others. For example: https://www.slideshare.net/...

Chris, Good luck in learning and congrats to you on the upcoming anniversary!

Thanks for the links Nicko

You are welcome, Chris

The Consonants section pronunciation sounds horrible, somebody needs to redo the voices, even my Korean friends are saying that . The Vowel Section sounds good though
