Sometimes you think something up and wonder whether you’re the first one to see it (it apparently being just a brilliant stroke of coincidence) or whether you’ve just come across the reason for it’s being as it is (the underlying idea or intentional correlation).
Well, I just had a little idea of the above category.
You know how people write “x” at the end of text messages and emails, meaning “kiss”. But why x? Is “x = kiss” just a random social convention, meaning kiss could also have been put down as “y” or “z” if it was widely enough used, or is there a more profound reason behind it?
Then my little thought came up. In Spanish the letter x is pronounced “ekys”, sounding somewhat like a Spanish person saying “a kiss” in English.
So does “x = kiss” perhaps originate from the Spanish? We will probably never be able to confirm that with all certainty.
