What does the verb 'effect' mean?

The verb 'effect' means to cause something to happen or to bring about a change. It implies a direct action that leads to a particular result or outcome. This definition aligns perfectly with the chosen answer, as it highlights the active role someone might take in creating change or in initiating a process.

In the context of the other options, 'to instigate change without any consequence' does not accurately describe 'effect,' since 'effect' specifically involves a tangible result. Similarly, 'to prevent something from happening' contradicts the meaning of 'effect,' as it suggests the opposite action. Lastly, 'to ignore or overlook' also diverges from the meaning of 'effect,' since it implies inaction rather than a decisive and impactful action. Thus, 'to cause something and make it happen' is indeed the most precise interpretation of the verb 'effect.'
