Do all native speakers know the words
Thee Thou Thine Thy ?
And all other forms of creating the sentences in the archaic manner?
I mean all these phrases and grammar aren't used by anyone now but known by every person or aren't known, either.
Because it's kind of amusing if nobody uses it but knows perfectly and one day some guys can go for a walk and use this archaic genre of talking to make a view of some noble people. And everybody will understand them if it's known by everyone.
P.S. I would be extremely pleased and grateful if you asnwered something using these adorable words...:)
