Root Explanation
Functioning → It is formed from "function" (from Latin "functio", meaning performance or execution) and "-ing" (a suffix used to indicate the action or process of). The word "functioning" refers to the action or process of performing a specific role or task.
Memory Tip
Think of 'function' as the act of 'performing' something, and the '-ing' shows that it is happening right now. This helps you remember that 'functioning' means actively performing a task.
