Many people search for “went into effect or affect” because English can be confusing—even for fluent speakers. These two words look similar, sound related, and are often mixed up in writing. You might see a sentence like: “The new law went into affect last week.” It feels right at a glance, but it’s wrong.
This confusion shows up everywhere: emails, news articles, social media posts, contracts, and school assignments. Writers want to sound professional, but one small spelling mistake can hurt clarity and credibility. That’s why this keyword is so popular—people want a quick, clear answer and a simple rule they can remember.
This article solves that problem step by step. You’ll get a fast answer, the history behind the words, British vs American usage, common mistakes, real-life examples, and practical advice on which spelling to use. By the end, you’ll confidently know when to write “went into effect” and why “went into affect” is almost always incorrect.
The Law Goes Into Effect or Affect
The correct phrase is “the law goes into effect,” not affect. In legal and formal English, effect is the right word because it refers to a result, outcome, or something becoming active. When a law goes into effect, it officially starts and must be followed. The word affect, on the other hand, is usually a verb that means to influence something, not to begin it.
Correct example:
✔️ The law goes into effect on January 1.
Incorrect example:
❌ The law goes into affect on January 1.
This rule is the same in American and British English. If you are writing about laws, rules, policies, or regulations starting on a certain date, always use effect. This keeps your writing clear, correct, and professional.
