What is meant by "order" in reference to ministries within the Church, and how did its usage come about?

FMS' answer to What are the positions relative to each other in the Catholic church's clerical hierarchy? mentioned a twofold hierarchy in the Church, that of **order** and that of **jurisdiction**. Given examples from the secular world, it is a bit easier to understand what is meant by *jurisdiction*. The question is, what is meant by *order* and how did its usage come about? **Note:** Please note @curiousdannii's comment that Anglicans also have a three fold order of ordination and a book called the Ordinal. Perhaps the answer will speak to the Anglican meaning so long doing so will not make this post off-topic.
