carpal

The Greek word karpos (καρπός) named the wrist long before anyone counted the bones inside it. Aristotle used the term in the 4th century BCE, referring not to individual ossicles but to the joint where arm becomes hand. The concept traveled into Latin as carpus, carrying the same broad meaning.

Galen of Pergamon, writing in the 2nd century CE, gave carpus its first anatomical precision. He described the small bones of the wrist region collectively, distinguishing them from the longer metacarpal bones extending toward the fingers. His texts, transmitted through Byzantine and Arabic translations, kept the word alive through centuries when direct Greek learning had faded in Europe.

The English adjective carpal arrived in the 17th century as anatomists built a shared Latin-derived vocabulary across Europe. Andreas Vesalius in 1543 had already used carpus systematically in De Humani Corporis Fabrica, and English physicians followed the Latin model. The plural carpals named the eight small bones: scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate, and hamate.

Carpal tunnel syndrome gave the word its modern ubiquity in the late 20th century. The carpal tunnel is the narrow passage through the wrist bones through which the median nerve and tendons pass. Repetitive strain brought this ancient anatomical term into everyday speech, and now millions know exactly where their carpals are.
