'Adventist' originates from the Latin word 'adventus,' meaning 'coming' or 'arrival,' combined with the suffix '-ist,' indicating a follower or member.

'Adventist' was derived from the term 'Advent,' which referred to the anticipated second coming of Christ, and evolved into the modern English term 'Adventist' to describe members of this religious group.

Initially, it referred to those who anticipated the second coming of Christ, and this meaning has largely remained the same in modern usage.
