Root Explanation

Dissertation → It is formed from "dis-" (meaning apart) and "serere" (meaning to join or to connect). The word describes a written work that is put together separately to present a particular argument or research.

Memory Tip

Think of a written work that is 'put together' ('serere') in a way that separates it from other works ('dis-'). This helps you remember that a dissertation is a distinct piece of writing presenting a specific argument.
