Just take 5 minutes to understand the logic behind it, watch it twice and you will see it is more effective than singing the alphabet. Thousands of people sing the alphabet and think they learn it that way,but when they need to spell out they need to be mentally singing_ let alone when they listen to someone spells words out at a normal pace of speech. Just try it and you will see what I mean. Happy Spanish Learning!

Although la Real Academia Española deleted those letters, many speakers still use them nowadays worldwide, that is why it is important for students to recognize them. And as for “ll”, again, some speakers say “elie” some others “doble ele”. I feel learners need to know them all as they may come across many different speakers from different areas, not just strict Real Academia followers. Thanks for your comment.

Depende de la variedad de español que uses. Los sonidos “Y” y “LL” son los que tienen mayor variedad de pronunciaciones- Pueden tener hasta 3 pronunciaciones diferentes.

There are three ways to pronounce that LL sound:
/i/ is one, another one is similar to /y/ and in Riverplate Spanish (Argentina and Uruguay) /sh/

However, most countries either use the /i/ or the /y/ form.

Yes, that is correct. But it is only a different way of saying the same. Some countries use one, some others use the other.

Hi, thanks for commenting. I feel it is very important to know some of these things to fully grasp how important it is the alphabet in Spanish. You know it and you know the sounds and man, you can actually say any word in Spanish! Happy Learning!

Correct me if I am wrong, but I think you did not understand what the person asked. He wants to know in terms of pronunciation. Even though in Spain you say “uve” to refer to “V” when you say it in isolation, the pronunciation is no different from “b” within a word….
For example …..the sound /v/ in vaca is no different from /B/ in bala…. So you have /va/ and /ba/ and the pronunciation is basically the same.
