A person or entity that assigns a task or authority to someone else.
From Latin delegatus combined with the agent suffix -or (meaning 'one who does'). This creates the parallel English pattern: one who delegates is a delegator, just as one who educates is an educator.
The Romans were brilliant at building word systems—by using -or to mark people who do things, they created a template that English borrowed wholesale, allowing us to generate hundreds of job titles and roles with predictable patterns.
