The phrase “middle name” first appeared in an 1835 Harvard University periodical called Harvardiana, but the practice dates back much further.

Yes … it goes back further to the Middle Ages where the ancient Romans used several names as privileges: the longer the name, the more privileged the person… You can find a lot on the Internet on this subject, but what is the middle name for us today, where we are usually called by one name: a privilege? a peculiarity? a secret? or rather a burden?
Many celebrities have this middle name. and if you google them properly, you will be surprised how they are called with middle names, or in most cases how they are called in reality. One can only dream that one will marry some day one of them, then one wants to make use of the (other) name with which nobody else speaks to her or which nobody else knows about it. ( just a funny idea!)
In the age of the social networks one could find some use for it, in which one indicates the middle name as aliases. This leads to a completely new topic: Why do people hardly give their true names as user names?
And this in turn leads to other unfortunately negative effects of using aliases: forgery, scammery, which is so common in social networks today as a plague, and nobody seems to care about it! It’s really sick and a warning to humanity that some might be so psychologically weird that they can even address other people in the name of others, quite apart from the other intentions of their action.
