Joined together or united as one, often used to describe conjoined twins (babies born physically connected).
From Old French 'conjoindre,' combining 'con-' (together) and 'joindre' (to join), ultimately from Latin 'iungere.' The term became medical terminology in the 19th century.
Conjoined twins have fascinated medicine and society for centuries—the most famous were Chang and Bunker, 19th-century twins connected at the chest who traveled the world as the 'Siamese Twins,' forever changing how people understood human variation.
