Frequently Asked Questions

What are word forms?

Word forms are different grammatical variations of a base word. For verbs, this includes conjugations like past tense and participles. For nouns, it includes plural forms. For adjectives, it includes comparative and superlative forms.

What's the difference between regular and irregular forms?

Regular forms follow predictable patterns (e.g., walk→walked, walks, walking). Irregular forms don't follow standard rules (e.g., go→went, gone; be→was, were, been).

Can I search by inflected forms?

Yes! You can search for any form of a word. For example, searching "went" will show you it's the past tense of "go", along with all other forms of that word.
