In English, we have the word "parent", which we can
use in talking about the set of parents. And we
can add the preposition "of" to talk about the
"parent of" relation. We do that with just one
noun and the option of adding a preposition.
We can use that same option with many other words,
such as "child", "employee", "client", etc.
That sounds rather simple. Why not do the same
in our notations for logic?
