Conlang, Glossolalia, daiin pronounced

[Rafal]

Must admit that I am not sure what „in tongues“ is supposed to mean; is it like babbling something?

My feeling is that this thread is a total mess.

I know what glossolalia in its standard meaning is  :a phenomenon or practice in which people utter words or speech-like sounds, often thought by believers to be languages unknown to the speaker
But I don't know what "Glossolalia" as understood by the author is:  an Angelic script with underlying Latin source code

"Speaking in tongues" is an imprecise phrase coming from the Bible. Sometimes it may mean the same as glossolalia, sometimes not.

One case is apostles speaking in foreign languages that they didn't know:

This thing is called "speaking in tongues" but it was not glossolalia but xenoglossy: You are not allowed to view links. Register or Login to view.

Another case are Christians from Corinhth who practiced prayer by ecstatic speech/babbling:

It is also called "speaking in tongues" and this was true glossolalia

But the author should really say how he understands these things as he probably has his own, private understanding of them.
