In English, some verbs are followed by the -ing form, while others are followed by the infinitive. There is no rule for which form to use, and it depends on the verb. Some verbs that are followed by the -ing form include enjoy, mind, stop, and recommend, while some verbs that are followed by the infinitive include want, learn, offer, and refuse. Some verbs can be followed by either form, with no change in meaning, while others have a change in meaning depending on the form used.
