1. directive

Today we are going to learn “directive”. Directive is an official order or instruction.
eg:
(1) The European Council recently adopted a directive on control of the acquisition and possession of weapons.
(2) As president, he will learn that he sends out a directive and nothing happens.

2. commencement

Another word is “commencement”. It means a ceremony at which university, college, or high school students receive their diplomas.
eg:
(1) In fact, you could be sitting three years from now waiting before commencement and you can get that grade adjusted.
(2) Oprah Winfrey was the commencement speaker at the Smith college graduation.
