What’s happening to our language? I don’t know what you are telling me when you insert “you know” at the beginning, middle or the end of a statement.
Sometimes it occurs several times in a statement. It is found in the speech of uneducated athletes to highly educated professionals. It is ubiquitous anywhere English is used, both spoken and written.
If “you know” was deleted from any statement, the meaning of the statement would not change. I am sure that I don’t “know” if used at the beginning of a statement.
I think I “know” if it is used at the end of a statement. I am unsure if I “know” when used multiple times throughout the statement.
