I am trying to tell the difference between 'al' and 'a' to refer to a place.
I know that you usually use a to refer to a country. But when should you use al?
I am trying to teach someone the difference but I don't really know how to explain it. I use it all the time as a native speaker, but to explain it is a different story. I tried looking on the internet only to find differences between hay/ahi/ay etc... not really al.
Ana y yo vamos a ir al bar.
*Ana y yo vamos a ir a bar. (I know this is incorrect. As to why, that is the question)
As per comments, then can I know when do I need the definite article "el"? Or if there is another explanation for al?
