"Millennial" Natural Recordings by Native Speakers
A millennial is a person who was born between the early 1980s and the late 1990s. The term is often used to describe the generation that grew up with the advent of the internet, social media, and mobile devices, and is characterized by their familiarity with technology and their preferences for digital communication.
Millenarianism is a belief or movement that expects a significant transformation or a dramatic change in the world, often associated with the idea of a thousand-year golden age or utopia. This transformation is usually attributed to the second coming of a messianic figure or a divine event, and is often a central tenet of various religious or esoteric groups. Typically, millenarian movements are characterized by a sense of urgency, a conviction that the expected transformation is imminent, and a willingness to sacrifice or take drastic measures to bring about the desired change.
Millenarians are individuals who believe that the world is about to come to an end or be dramatically transformed, often due to some catastrophic event, and that a new millennium or era will be ushered in as a result. This term is often associated with apocalyptic or prophets who predict the end of the world or a major transformation.
Millennia refers to a period of one thousand years. For example, the 1st millennium refers to the period from 1 AD to 1000 AD, and the 2nd millennium refers to the period from 1000 AD to 2000 AD. The term is often used to describe long periods of time, such as geological eras or historic events.
I apologize, but there is no word "millennist". It's possible that you meant "millennialist" or "millenialist", which refers to a believer in the doctrine that Christ's second coming and the end of the world will occur within a thousand years after his ascension.
