Expert writing Tips

Best practice

Use "took effect" when referring to a specific date or time when a new rule, law, or policy became operational. For example: "The new regulations "took effect" on January 1st."

Common error

Avoid confusing "took effect" with 'affected'. "Took effect" means something became operational, while 'affected' means something was influenced or impacted. For example, it's incorrect to say "The policy affected on January 1st"; instead, use "The policy "took effect" on January 1st".
