How much per say?

[vakkotaur]

per se -- by, of, or in itself; as such; intrinsically (source: Webster's Ninth New Collegiate Dictionary.)

I am noticing, with increasing frequency, that per se is being replaced with "per say." While they sound the same, which is the source of the problem, they are different. The term per se is Latin or at least derived from Latin, while "per say" is a pair of English words.

I wonder what "per say" could be used for? Speech that is limited in some way? "You will have your say, but you only have five minutes per say."
