jacquard card
C2 (Very Low Frequency)Technical/Historical
Definition
Meaning
A perforated paper card used to control the pattern woven by a Jacquard loom.
In historical computing, a punched card using the same principle as a Jacquard card for data storage and program control.
Linguistics
Semantic Notes
A highly specific term from weaving and early computing. Refers to the physical medium, not the loom itself.
Dialectal Variation

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'карта Жаккарда' (implies a map). The correct term is 'перфокарта Жаккарда' or simply 'жаккардовая перфокарта'.
- Do not confuse with 'jacquard fabric' ('жаккардовая ткань'). The card is the control mechanism for making that fabric.
Common Mistakes
- Spelling: 'jacard card', 'jackard card'.
- Using it as a verb (e.g., 'to jacquard card the design').
- Confusing it with the modern, electronic Jacquard machine head.

FAQ
Frequently Asked Questions
In principle, yes. 'Jacquard card' refers specifically to the cards used in Jacquard looms, which were the historical prototype for the punched cards later used in early computing.
It would be historically inaccurate. While conceptually identical, in modern technical English, 'jacquard card' is reserved for the weaving context, and 'punched card' or 'punch card' for computing.
No. While derived from the inventor's surname (Joseph Marie Jacquard), it is now a standard common noun (like 'diesel' or 'boycott') and is not capitalised.
It represents a key conceptual bridge between mechanical automation (weaving) and programmable machines, directly influencing the development of computers.
