Non-personal forms
Non-personal forms are verb forms that do not name the subject. They do not change for I, you, or he. They include the infinitive, like to go, the -ing form, like going, and the past participle, like gone. We use them after some verbs, or as nouns and adjectives.
Gerund (-ing)
A1A gerund is a verb ending in -ing that is used like a noun. It can be the subject of a sentence, as in “Swimming is fun,” or the object, as in “I like reading.” We often use it after words like enjoy, like, love, and hate, and after prepositions.
Infinitive
A1The infinitive is the base form of a verb. It often comes with “to”, like “to go”, “to eat”, or “to see”. We use it after many verbs, for example “want to go”. We also use it to explain a purpose, like “to learn English”. It does not change for time or person.
Participle
B1A participle is a verb form. It helps build verb tenses and can also describe a noun like an adjective. The present participle ends in -ing, like running. The past participle often ends in -ed, like played, but some are irregular, like gone.
