parliament: [13] The French verb parler ‘talk’ has made a small but significant contribution to English. Amongst its legacies are parlance [16], parley [16], parlour [13] (etymologically a ‘room set aside for conversation’), and parliament itself. This came from the Old French derivative parlement, which originally meant ‘talk, consultation, conference’, but soon passed to ‘formal consultative body’, and hence to ‘legislative body’. French parler was a descendant of medieval Latin parabolāre ‘talk’, which was derived from the Latin noun parabola (source of English parable, parabola, and parole).

c. 1300, "consultation; formal conference, assembly," from Old French parlement (11c.), originally "a speaking, talk," from parler "to speak" (see parley (n.)); spelling altered c. 1400 to conform with Medieval Latin parliamentum.

Anglo-Latin parliamentum is attested from early 13c. Specific sense "representative assembly of England or Ireland" emerged by mid-14c. from general meaning "a conference of the secular and/or ecclesiastical aristocracy summoned by a monarch."
