This question already has an answer here:
I was just looking into properties of languages and wondered about the cardinality of them
are all recursive languages countable or can they also be uncountable (can u have a recursive language which is uncountable?)
can r.e languages be countable and uncountable? (can u have a r.e but not recursive language which is uncountable?)
are all non r.e languages uncountable? (can u have a non r.e language which is countable?)
an explanation would be nice but i am not necessarily looking for a proof. thanks!
