Detect accidentally repeated adjacent words in your text (e.g. 'the the').
How it works
Accidentally repeated adjacent words -- such as 'the the' or 'is is' -- are a common typing error that spell checkers often miss because both individual words are spelled correctly. This tool scans your text and flags every instance where the same word appears twice in a row.
Paste your text and the tool checks each consecutive word pair. It reports the duplicated word and the position in the text so you can locate and fix each one quickly. The check is case-insensitive, so 'The the' is also caught.
This is a fast final proofreading check before publishing any long-form content, sending an important email, or submitting a document. It takes seconds and catches errors that are easy to overlook when reading your own writing.
Worked example
Proofread a press release before sending
- Paste the complete press release text into the field.
- Click Check.
- Review the list of flagged duplicates, e.g. 'the the' at position 47.
- Locate each error in your original document and delete the extra word.
All accidental duplicate-word errors identified and ready to fix.
Common mistakes to avoid
- Assuming your word processor's spell checker already caught these -- most do not flag correctly spelled duplicate words.
- Only checking the final draft -- duplicates often appear during editing when sentence fragments are merged.
- Ignoring the tool's position indicator and searching manually in a long document -- use your editor's Find function to jump directly to the reported position.
Key terms
- Adjacent duplicate
- Two identical words appearing consecutively in text, e.g. 'that that', usually a typing or editing error.
Frequently asked questions
- Does this catch non-adjacent duplicates?
- No — this tool only flags words repeated consecutively (e.g. 'the the'). Use the Keyword Frequency tool to find words repeated throughout the text.
- Is the comparison case-sensitive?
- No — 'The' and 'the' are treated as the same word when checking for adjacent duplicates.
