Anything that serves as a safety or protection measure acts as a parapet. Thus, a wall or a grid built to prevent falls is a parapet. The same applies to a wall, a fence or a trench.
A word of military origin that has adapted to other circumstances
As for the origin of the term, it comes from the Italian word parapetto, which, in turn, comes from the expression “parare il petto”, which can be translated as protecting the chest. The original parapets referred to all the elements of military defense that allowed soldiers to protect themselves from enemy attacks, especially from cannon balls. In this sense, the parapet is an element of military protection, however, it has already been extended to the field of architecture and engineering, as in these areas it is necessary to resort to measures to avoid possible risks or accidents.
from parapet to parapet
From the noun parapet, the verb parapeitar is formed. So, when someone wants to protect themselves from the rain and gets under an awning, they are parapeting, that is, protecting themselves. The term parapet is not at all common and is synonymous with taking shelter, covering oneself, taking shelter or defending oneself.
The action of parapeting can be understood in a double sense: as an element of physical protection or as a way to protect oneself psychologically.
How we parapet psychologically
We often have feelings of fear, feel vulnerable, or simply don’t want others to know about us. In all these circumstances we need a strategy to serve as a parapet.
Let’s think about using the sir treatment instead of you. When we resort to the use of a lord, we do this out of politeness or to establish a certain distance from someone. The fact of resorting to a lie to refer to our responsibility is also a way to protect us, that is, to parapet.
Using an excuse for not meeting a commitment is another way to avoid problems. In summary, psychological parapets are mental mechanisms that allow a better adaptation to circumstances.
Sometimes these mechanisms are unconscious and psychoanalysis calls them defense mechanisms. Among the defense mechanisms of the unconscious type, we can highlight two: denial and projection. We use denial when we accept something we find painful and we use projection when we blame our mistakes on others.
