lords, chancellors, lord chancellors, attorney generals?

Question

Please explain the differences. Also what was Thomas More's function as a Chancellor (apart from loosing his head)?

Answer 1

A Lord (Laird in some Scottish contexts) is a male who has power and authority. It can have different meanings depending on the context of use. Women will usually (but not universally) take the title 'Lady' instead of Laird or Lord. Two examples of a female Lord are the Lord of Mann, or the current Lord Provost of Edinburgh.

Chancellor or chancellour (archaic) (Latin: cancellarius) is an official title used by most of the peoples whose civilization has arisen directly or indirectly out of the Roman Empire. At different times and in different countries it has stood for various duties and has been borne by officers of various degrees of dignity. Various governments have a chancellor who serves as some form of junior or senior minister. The original chancellors were the Cancellarii of Roman courts of justice - ushers who sat at the cancelli or lattice work screens of a basilica or law court, which separated the judge and counsel from the audience. A Chancellor's office is called a chancellery or chancery.
