History behind the term 'Sibling'


The Birth of 'Sibling'

The term 'sibling' originated around the year 1150, derived from the Old English word 'sibb', which means 'relative' or 'kinsman'. It was originally used in a broader sense to refer to any blood relative or family member, not specifically limited to brothers and sisters.


Narrowing of the Definition

By the 14th century, the meaning of 'sibling' began to shift, narrowing down to specifically refer to brothers and sisters. This change in definition was a gradual process as the term gained more common usage to describe the relationship between children of the same parents.


Inclusion in Modern English

In 1903, the term 'sibling' was officially recognized and included in the Oxford English Dictionary, solidifying its place in the modern English language. From then on, it became a commonly used term to signify the relationship between brothers and sisters.


Psychological Significance

In 1947, psychoanalyst Sigmund Freud introduced the concept of 'sibling complex' or 'sibling rivalry' in his book 'The Wolfman and Other Cases', highlighting the psychological significance of the sibling relationship. This concept explores the competition, jealousy, and conflicts that can arise between siblings, shaping their emotional development.


Recognition of Non-Binary Siblings

In more recent years, as societal understanding of gender has evolved, the term 'sibling' has expanded beyond the traditional binary definition of brother and sister. It is now widely recognized and embraced as an inclusive term to encompass non-binary siblings and individuals who may not identify within the gender binary.
