punch-card

The term 'punch-card' is a transparent compound describing a specific technological artifact. The first element, 'punch', carries its core meaning of perforating or making a hole by force, a concept with ancient roots possibly linked to the Latin verb for pricking. The second element, 'card', traces back to the Greek word for papyrus sheet, evolving through Latin and French to denote a piece of stiff paper. Combined in the late 19th century, the term literally means a "card for punching holes into," which perfectly captures its function as a physical medium where strategically placed perforations encoded information for mechanical reading and data processing.

Structure: punch (to make a hole) + card (stiff paper) punch: From Middle English punchen, meaning "to prod, pierce". Its ultimate origin is uncertain but may be related to the Latin pungere, "to prick". card: From Middle English carde, from Old French carte, from Latin charta, "paper, papyrus", from Greek khartēs.
