parliament (n.) Look up parliament at Dictionary.com
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."
