Information Purpose

PlainSpell is an informational language resource that presents word definitions, pronunciations, confusable pairs, homophones, and misspelling corrections sourced from Wiktionary data. The information on PlainSpell is provided for general informational and educational purposes only and should not be relied upon as a substitute for professional language authorities or academic dictionaries.

Data Attribution (CC BY-SA 3.0)

Word definitions, pronunciations, and etymologies displayed on PlainSpell come from Wiktionary contributors and are licensed under the Creative Commons Attribution-ShareAlike 3.0 Unported License (CC BY-SA 3.0) . Under this license, you may share and adapt this content provided you:

Data Accuracy and Verification

PlainSpell aggregates and reformats information that originates from openly-licensed public language datasets, primarily Wiktionary (via the kaikki.org extract, CC BY-SA) and an open word-frequency list, together with algorithmically generated spelling variants. While we take reasonable steps to ingest, normalize, and refresh this data, upstream records may contain errors, lag behind real-world usage, or omit relevant context. You are solely responsible for verifying any spelling, definition, or usage fact that influences a consequential decision. Cross-reference the original source before relying on anything you read here.

Acceptable Use

You may browse, read, and share PlainSpell content for personal, journalistic, academic, and non-commercial research use. You may cite specific records with attribution and a link back to the page on plainspell.com. You may not (a) systematically scrape, crawl, or download the dataset in bulk without prior written permission; (b) resell, sublicense, or redistribute derived data products that compete with PlainSpell; (c) use our pages to harass, defame, or misrepresent any individual or organization appearing in the data; (d) remove, obscure, or mislabel source attribution; or (e) attempt to bypass rate limits, security controls, or authentication mechanisms.

Editorial Process

PlainSpell combines openly-licensed dictionary data with plain-language summaries, explainers, and comparisons. Narrative sections are drafted by our editorial team from the source data. We do not alter underlying definitions, pronunciations, or frequency values, those are loaded directly from the upstream Wiktionary and word-frequency sources. If you spot a summary that misreads the data, please email the correction link on our contact page.

Intellectual Property

The underlying dictionary records surfaced on PlainSpell are freely licensed by their upstream projects (Wiktionary contributors under CC BY-SA; the word-frequency list under its open licence), and you are free to use those raw facts under those same terms. However, our site design, layout, navigation structure, original editorial copy, category taxonomies, comparison tables, and curated rankings are the copyrighted work of PlainSpell. These creative elements may not be reproduced in whole or substantial part without permission.

Changes to These Terms

We may update these Terms of Use from time to time to reflect changes in our data sources, product features, legal environment, or advertising relationships. When we make material changes, we will update the "Last updated" date above and, when appropriate, surface a brief notice on the homepage. Continued use of the site after an update constitutes acceptance of the revised terms. We encourage you to revisit this page periodically.

Governing Law and Disputes

These terms are governed by the laws of the United States and the jurisdiction in which PlainSpell's publisher is domiciled, without regard to conflict-of-law principles. Any dispute arising from or relating to your use of PlainSpell will first be addressed through good-faith informal negotiation. If that fails, both parties agree to resolve the dispute in the courts with jurisdiction over the publisher's principal place of business. Nothing in these terms limits your statutory consumer-protection rights under applicable local law.

Legal Notices

For formal legal notices, DMCA takedown requests, subpoenas, law-enforcement requests, or correspondence regarding these terms, email legal@plainspell.com. General questions, data corrections, and feedback should use the contact page so they reach the editorial team promptly.
