Conjugate a verb or find all forms of a word. This interface provides inflectional variants for words in a large English dictionary. It is not necessary to know the lemma of a word or the infinitive form of a verb. If you input the word "went", for example, the interface provides the conjugation for the verb "go". Similarly, entering the word "child" displays the singular, plural, and possessive forms of the word. Words that have multiple parts of speech, e.g., "stop", display both the noun and verb paradigms. Adjectives and adverbs display the positive, comparative, and superlative forms. Spelling aid is provided for words that cannot be found in the dictionary.
Regular verbs in English are conjugated using the infinitive for all forms, except that the past and past participle end in "ed", the present participle ends in "ing", and the third person singular ends in "s". Although the rules appear to be very simple, the morphology of regular English verbs is affected by phonetic and orthographic constraints.
Irregular verbs do not follow the standard patterns of conjugation. There are approximately 200 irregular verbs that are commonly used.
