What does proper mean?
Proper is an adjective with several closely related meanings. At its most common, it describes something that is correct, suitable, fitting, or appropriate: using the proper tool or following the proper procedure. It can also mean genuine or actual, as when someone distinguishes a proper meal from a snack, or the proper name of a product from its model name. In a social register, proper suggests respectable behavior, politeness, or conformity to accepted standards, though this use can sound formal or old-fashioned. In grammar, a proper noun is a name identifying a particular person, place, organization, or thing, and is normally capitalized. The word is useful because it combines ideas of correctness, suitability, authenticity, and belonging to a specific category, while its intensifier use adds an emphatic, informal note in British speech.

Where does proper come from?
English proper came through Anglo-French from Latin proprius, meaning “one's own,” “particular,” or “belonging to one.” Its older sense of what belonged to someone developed into the modern ideas of what is fitting, rightful, or appropriate. The same Latin root underlies words such as property, proprietor, propriety, proprietary, and appropriate.
