This is a question my High School English teacher could not answer 20-odd years ago and every time I encounter it, it bugs me. I only know what it means in terms of other phrases such as 'per se'.
I have a general idea what it means, but I can't really wrap my head around it. 'As it were' when exactly?
Does anyone know the origin?

The phrase is theoretically short for as [it would be if] it were [so], though it is uncertain whether that is really where it came from.
