'Parliament' is literally 'a place of speaking' — kin to 'parlor' (a talking room) and 'parole' (a given word).
The highest legislature in certain countries, especially the United Kingdom, consisting of the sovereign, the House of Lords, and the House of Commons.
From Old French 'parlement' (a speaking, a discussion, a conference), from 'parler' (to speak), from Late Latin 'parabolāre' (to speak, to talk), from Latin 'parabola' (a comparison, a parable, a speech), from Greek 'parabolē' (a comparison, a placing beside), from 'para-' (beside) + 'ballein' (to throw). A parliament was literally 'a speaking' -- a place where people came to talk. The same deep root connects to 'parable,' 'parole,' and even 'palaver.' Key
