"Another place" or "the other place" is a euphemism used in many bicameral parliaments using the Westminster system (including Australia, Canada and the United Kingdom) and several rival educational establishments.
So, for example, a member of the Senate of Canada would not mention "the House of Commons" but would use the phrase "the other place".
[1] The reasons for the tradition are unclear, but it has been suggested that it dates back to a period of ill-feeling between the two houses of the UK Parliament.
Similarly a member talking of their own house would refer to it as "this place".
The universities of Oxford and Cambridge refer to each other as "the other place",[2][3][4] as do the pupils of the British public schools Eton and Harrow.
