라 [ra] or [la], you know the musical scale, la
랴 [rya] or [lya]
러 [ro] or [lo] / [rʌ] o [lʌ] but, I recommend you pronounce like [lo-] in 'love'
려 [reo], [leo] [rio] [lio] its sound is quite hard to explain but think about 'Korea', and the word "Korean" is originally came from "고려" and you can make this sound to say [lio] quickly
로 [ro] or [lo], it looks confusing with 러 but it is more like [ro] in rod or [lo] in lord
료 [ryo] or [lyo] - You just make sound r or l +'yo' quite quickly and you can make the sound of 료. Yo girl, you can do this!
루 [ru] or [lu] but its sound is actually the same as "loo' as toilet in British English.
I go to the loo to pee
류 [ryu] or [lyu], I think I will be easy. Do you know the famous actress, Lucy Liu? Its sound is more like Liu in her name.
르 This is the most difficult part because you didn't use vowel 'ㅡ' Think about 'pro-' in professor.
How can you make the sound pr ? There, you just pronounce p without any vowel, right? The sound of ㄹis made that way. We must use the combination of consonant and vowel, so we put the vowel 'ㅡ' under the any consonant, 그/느/드/르/므/브/스/으/즈/츠/크/트/프/흐 etc.
So, I might say, you can make sound 'lm' for 름 and 르 sound can be R in 'Rwanda"
리 You know this sound, lee, the famous jean make.
말을 I will write down the way I hear its sound
[ma-rul]
You shouldn't say 말 and 을 separately
How can you say 'want to' ?
Like the same way, you can make the sound as 마+를.
