About VerbVerb
VerbVerb helps you look up and practise verbs in foreign languages. You don't need an account.
If you turn it on under Practice, your browser remembers which verb forms you got wrong. That data stays on your own device and is never sent to a server.
We count visits with Cloudflare Web Analytics. It works without cookies and without personal data: we only see how often pages are viewed.
Sources and licences
We use several sources for the verb forms, the checks and the order of the results:
French
- Conjugations: Verbiste, under the GPL v2 licence.
- Technology: verbecc 2.0.3, under the LGPL v3 licence.
- Checks: Wiktionary via kaikki.org, under the CC BY-SA licence.
- Order ‘Most common’: Lexique 4 (lexique.org). The frequencies are based on 316 million words from film and series subtitles and fall under CC BY-SA 4.0.
German
- Conjugations: german-pos-dict by LanguageTool, via the npm package german-verbs-dict, under the CC BY-SA 4.0 licence. We bring old spellings (muß, wußte) up to date and add the auxiliary (haben or sein) ourselves.
- ‘Most used’ order: wordfreq (CC BY-SA 4.0), which counts how often words occur in subtitles, Wikipedia, books, news and web text. We add up all forms of a verb.
How do we check the conjugations?
We automatically compare every verb form with Wiktionary.
If our sources give different forms, we check which one is right in a trusted reference, such as the Bescherelle. We show the standard form first. We put an accepted variant next to it in smaller type. That variant also counts as correct when you practise. For example: je puis next to je peux.
The explanations of the tenses are based on the Bescherelle, Grevisse's Le Bon Usage and the Vitrine linguistique of the Office québécois de la langue française.
The German explanations are based on Duden – Die Grammatik, Duden – Richtiges und gutes Deutsch and Hammer’s German Grammar and Usage.
Where a grammar rule has exceptions, we say so with words like ‘usually’ or ‘rule of thumb’.
