IPA: /kəˈmɛnsmənt/
KK: /kəˈmɛnsmənt/
A ceremony or event where degrees or diplomas are given to students who have completed their studies, often marking the end of an academic program.
The commencement ceremony will take place in the university auditorium next Saturday.
Commencement is formed from "com-" (meaning together) and "ment" (from Latin "mentum", meaning the result of an action). The word refers to the act of beginning something together, often used in the context of graduation ceremonies marking the start of a new phase in life.
Think of 'together' ('com-') and the 'result of an action' ('ment') to remember that 'commencement' signifies the beginning of something significant.
