Advent means waiting for some thing to happen. an adventist in religious terms means anyone who is waiting for Jesus to return according to scripture. John 14 v 1-3. Another answer:
The word "advent" refers to the coming of something or someone (as in "the advent of the personal computer"). An Adventist (in theology) is someone who believes in the soon return of Jesus Christ at the Second Coming. The connotation is often that he or she is also waiting for that event with anticipation, but the word itself only denotes the belief in it as a real future event. The largest Adventist denomination is the Seventh-day Adventist Church, often referred to as simply the "Adventist Church".
