Anyone who has typed “Per Se vs Per Say” into a search bar has probably paused halfway through, unsure whether it ends in “se” or “say.” The confusion is completely understandable because of how the words sound out loud.
The short answer is that per se is the only correct spelling. Per say is simply a phonetic misspelling that happens because the Latin phrase is pronounced almost exactly like the word “say.” Once you understand where the phrase comes from, the confusion tends to disappear for good.
Per Se or Per Say: Which One Is Correct

Is Per Say Ever Correct?

Why Do People Spell It Per Say?
People rely on how a phrase sounds rather than how it is written, and the second syllable of per se sounds almost identical to the word say.
What Does Per Se Mean?
Per se translates loosely as “by itself,” “in itself,” or “intrinsically.” It is used to isolate one specific quality of something from the larger picture surrounding it.

Where the Phrase Came From?
