Inflected Forms of Verbs

A typical English verb may have five different inflected forms:

• the base form or plain form (go, write), which has several uses – as an infinitive, imperative, present subjunctive, and present indicative except in the third-person singular;
• the -s form (goes, writes), used as the present indicative in the third-person singular;
• the past tense or preterite (went, wrote);
• the past participle (gone, written) – this is identical to the past tense in the case of regular verbs and some irregular ones;
• the -ing form (going, writing), used as a present participle, gerund, and (de)verbal noun.

The verb be has a larger number of different forms (am, is, are, was, were, etc.), while the modal verbs have a more limited number of forms. Some forms of be and of certain other auxiliary verbs also have contracted forms ('s, 're, 've, etc.).
