Definition of the word triplicate

The word "triplicate" derives from the Latin prefix "tri-" meaning "three" and the Latin noun "plicare" meaning "to fold." In its original form, the Latin word was "triplices," which referred to a legal document that was required to be submitted in three copies. This Roman legal tradition continued throughout Europe during the Middle Ages, where "triplicate" came to mean any document that was required to be submitted in three copies as a legal requirement for official recognition or approval. This use of the word can be seen in various historical documents, such as the Magna Carta and the Articles of Confederation. In modern usage, "triplicate" has expanded to include various situations where three copies of a document or item are made, such as for backup or record-keeping purposes. It can also be used in more informal contexts, such as when ordering duplicate tickets for an event or asking for additional copies of a receipt. The term "triplicate" is still commonly used in legal, medical, and other official contexts today.
