Definition of improper

The word "improper" originally derived from the Latin phrase "proprum" which means "one's own" or "belonging to oneself." When applied to language or behaviour, the term "proper" referred to that which was acceptable or appropriate in a particular context. Conversely, "improper" referred to the opposite - behaviour or language that was unacceptable, inappropriate, or contrary to one's own personal beliefs or norms. In the English language, the word "improper" first appeared in the late 14th century. Its initial use was associated with religious contexts, where it referred to behaviour or actions that were not in accordance with religious principles or scripture. Over time, the meaning of the word expanded to encompass a broader range of contexts, such as social customs, manners, and propriety. In modern usage, the word "improper" is often used to describe actions or behaviour that contravene specific norms, standards, or expectations. Its use can also imply a deviation from correctness or strict adherence to rules or principles. In summary, the origin of the word "improper" can be traced back to the Latin term "proprum," which denoted "own" or "belonging to oneself." Its initial usage was linked to religious contexts, but over time, its meaning expanded to refer to actions or behaviour that were contrary to certain norms, standards, or expectations.
