Selah meaning?

[Student]

Salaamun Alaykum,

Sir Joseph, if you happen to read this post can you please let us know the meaning of Selah? I tried to find it and it appears there's none agreed upon:

Its etymology and precise meaning are unknown.

Anyone well versed in Hebrew and other language of previous scriptures are most welcome to comment and shed some light 

Thanks,
