It’s “All of A Sudden” not “All of THE Sudden”

There are right ways to do things and wrong ways to do things. This is the wrong way to do things.

“All of THE sudden, there it was.”

I don’t know where you people are picking this up from. Perhaps you’ve hopped in a time machine and gone back to the 1500s recently.

But the correct idiomatic phrase in English is “All of a sudden.”

So just stop it. Drives me crazy.
