Advanced reporting verbs have different grammar patterns and cannot be used interchangeably.
Some verbs take an object + infinitive, some take a gerund, and others take a preposition + gerund.
Choosing the correct pattern makes summaries of arguments and speech more precise.
| Use | Pattern | Example |
|---|---|---|
| Core form | verb + object + to-infinitive | They urged residents to evacuate. |
| Variation | verb + -ing | She denied leaking the document. |
| Advanced form | verb + preposition + -ing | He apologised for interrupting the meeting. |
Accuse takes object + of + -ing: They accused him of hiding evidence.
Warn can take object + not + to-infinitive or object + against + -ing.
