subpoena

Etymology

It is inherited from Middle English sub-pena, also suppena,^[2][3] borrowed from Medieval Latin sub poenā (“under a penalty”),^[4][5][2][6] the first words of the writ, which ordered a person to appear under a penalty for failing to.^{[7][4][8][3][9]} The OED treats the phrase as classical Latin, and compares Anglo-Norman sub pena, recorded for such a writ from 1465, the earlier phrase brief sub pena from 1416, and the post-classical Latin use from 1503.^[7] It is formed from sub (“under”) and poena (“penalty”), here in the ablative,^[4][5][6] the Latin noun also behind pain and penal.^[8][4]

Earliest recorded meaning

A writ ordering a defendant to come before the court to answer a charge, under a penalty for not doing so: before 1426, in the records of the Court of Chancery.^[7][2] Barnhart dates sub pena to 1422–61.^[6]

Semantic evolution

The Middle English writ was chiefly one of the Court of Chancery,^[2] and Merriam-Webster still records the process by which a defendant in an equity suit is summoned to answer the plaintiff's bill.^[3] From 1467, in the Paston letters, a subpoena could also summon a witness to give evidence,^[7][2] the main sense today.^[10][11] The Latin phrases subpoena ad testificandum, to testify, and subpoena duces tecum, to bring documents, are recorded from 1594 and 1730.^[7][9] A figurative use, something that summons or demands, appeared in 1593.^[7] The verb, to serve with a subpoena, is recorded from 1640,^[7][3][6] from the 1630s in Etymonline.^[4] Since 1869 it can also take a document as its object.^[7][10]
