  • US: /ˌpɑɹləmənˈtɛɹiən/[1]

Etymology

It is formed from English parliament + -arian.[2][3][4][5] Etymonline instead derives it from parliamentary with -ian.[6] The OED compares the earlier nouns parliamenteer and parliament man, and for the adjective the earlier parliamentary and parliamental.[2] Parliament itself is from Old French parlement (“a speaking, talk”), from parler (“to speak”).[6]

Earliest recorded meaning

The first record, from 1605, has a sense that died out within a few years: a person who accepts a religion or church ordained or ruled by parliament.[2][3] Dictionary.com dates the word to 1605–15.[4]

Semantic evolution

The word found its lasting use in the English Civil War, for a supporter of Parliament against the King, a Roundhead: from 1642 in the OED,[2] in the 1640s in Etymonline,[6] 1642 in Merriam-Webster Unabridged[5] and 1644 in Merriam-Webster's Collegiate.[7] In this historical sense it is usually capitalized.[2][5] The adjective, relating to a parliament or to the Parliamentarians, is recorded from 1647.[2] From 1834 a parliamentarian was a Member of Parliament, especially one skilled in parliamentary procedure and experienced in debate.[2][6][3] From 1889 the word was extended to members of other parliaments, at first a member of a French parlement.[2] It also names an expert in the rules of a parliament or other deliberative assembly.[5][8][7][9]
