Start with act as a verb: doing something or performing. Use this as the centre of your map, then attach action, actor, active and react.
Compare each branch
action names a process, actor a person, and active a quality. The displayed act + -ion, act + -or and act + -ive splits are teaching representations from the app, not claims about every historical formation step.
Read react in context
In react, re- + act points to responding or acting back. Do not always translate re- as “again”: reacting to a question is responding to it, not simply repeating an action.
Use the whole word
Try a short sentence such as “The actor is active.” Explain why actor is the person and active describes that person. Reuse the connection, but learn each word’s own usage.

Show a suggested answer
actor names the person. active is an adjective describing activity or energy; it does not name the performer in this sentence.
