Definition of norm

The word "norm" is derived from the Old French word "norme," which in turn came from the Latin word "norma." In medieval times, a "norma" referred to a carpenter's square, a carpentry tool used to ensure that perpendicular walls and surfaces were built correctly. This "norma" was considered the standard or ideal model for right angles, and its meaning shifted over time to denote an accepted standard in various contexts. In the 16th century, "norma" began to take on the meaning of a model, a pattern, or a rule that was followed as a guide or standard in various situations. This use of the term "norma" eventually led to the modern English word "norm," which is defined as a standard, a typical or typicals, or an average or average value. The word "norm" also has social and psychological connotations. In sociology and psychology, a "norm" is a social standard or rule, which is internalized by individuals in a culture or community, and conforms to certain expectations or behaviors shared by most people within the group. The term implies a sense of conformity, regularity, and consistency in human behavior. In summary, the word "norm" has its origins in an Old French word for a carpentry tool, which evolved through its use as a model or standard, and came to describe a social, psychological, or statistical standard or value.
