plaintiff

Pronunciation

• /ˈpleɪntɪf/^[1]

Etymology

It is inherited from Middle English plaintif, also playntyf and pleyntyff,^[2][3][4] borrowed from Anglo-Norman pleintif, also plaintif,^[5][6][7] the noun use of Old French plaintif (“complaining; wretched, miserable”),^[6][5][2] which in law meant "aggrieved".^[6] The Old French adjective is from plainte, plaint,^[6][8][9] which goes back to Latin planctus (“lamentation”), from the past participle of plangō (“to strike, beat one's breast, lament”).^[3] The OED records the noun in Old French from 1260 for the party bringing a suit,^[5] and the Anglo-Norman word from about 1235.^[7] It was at first the same word as plaintive; the form that came down through Law French and stayed in legal use kept the older spelling with “-iff”.^[6][10][11] Weekley compares complainant.^[12]

Earliest recorded meaning

In law, the party that brings a suit in a court, the opposite of the defendant: before 1325, in a manuscript of the Statutes of the Realm.^[5] Barnhart dates it before 1400,^[2] and Etymonline about 1400.^[6]

Semantic evolution

The legal noun has kept its meaning; the more general use for anyone who complains, recorded from about 1439 in Lydgate's Fall of Princes, died out after 1672,^[5][11] and a rare sense "a person who is unwell" is recorded only in 1633.^[5] Figurative and extended uses date from 1589.^[5] Johnson (1755) entered both the noun, opposed to the defendant, and an adjective "complaining", which he called a word not in use.^[13] In American law it is the party seeking a remedy for an injury to its rights, and Merriam-Webster contrasts it with the prosecutor as well as the defendant;^[14] Collins marks the word as former usage in Britain, now replaced by claimant.^[8]
