Proper is a term often used deliberately in a dual sense.
Related: Ambiguity
The dual nature of the term Proper suggests on the one hand the so-called by feminists “father’s law”. That is the tensions and prohibitions that often come from the male side, but are absolutely necessary for the growth of the child as a person and a citizen. Along with this “father’s law”, the meaning of proper includes “that which bears the father’s name”. That is someone’s own name.
On the other hand, proper also means meaningful or belonging to someone, the latter often being considered the same.
