What Happens Next

  1. We read your question

    Every message is read by a person. We look at the full sentence and the context you give, because the right answer often depends on it.

  2. We check the references

    We compare the mainstream American references, such as Merriam-Webster, Chicago and AP, and note where they disagree.

  3. You get a plain-English reply

    We email you the rule, a corrected example and a link to the guide that explains it. Popular questions may become new articles, without your name.

Keep private details out of your sentence. If you are asking about a work or school document, replace names, numbers and confidential details with placeholders. Learn how we handle your information in our Privacy Policy.

Before You Ask

Many questions are already answered in our guides. If yours isn’t, these details help us give you a precise answer on the first reply.

  • The full sentence

    A single word is often ambiguous. Whether you need affect or effect depends on what the rest of the sentence is doing, so paste the whole thing.

  • Your style guide

    AP, Chicago, APA and MLA disagree on commas, numbers and capitalization. Tell us which one your school or employer uses, if you know.

  • Your audience

    A text to a friend, a cover letter and a client email follow different rules, especially for slang, contractions and emoji.

  • A quick search

    Try the site search first. Our tricky words guide alone answers dozens of common questions.
