accessibility

(noun)

pronunciation:

əkˌses.əˈbɪl.ə.ti

The quality or condition of being accessible (capable of being reached, used, seen, understood or appreciated).

Etymology

Latin: accessus

Middle French: accessible

Middle English: accessyble

Modern English: accessible

The word "accessible" originates from the Latin "accessus," meaning "approach" or "entrance," which is derived from the verb "accēdere," signifying "to come near."

It was later borrowed into Middle French (14th to 17th century) as "accessible" and then transitioned into Middle English (12th to 16th century) as "accessyble," retaining its core meaning of being easy to approach.

The modern English form, established around the 15th century, expanded its scope over time to include not just physical approachability but also intellectual and conceptual accessibility.

The term has continued to evolve, particularly in the 20th century, where it became integral to discussions on inclusivity in technology, design, and society.
