Besides simple infinitives like (to) write, there are also progressive, perfect and passive infinitives.
Form: (to) + be + present participle
The progressive infinitive is used to suggest that actions and events are/were/will be continuing around the time we are talking about.
Form: (to) have + past participle
Perfect infinitives can have the same kind of meaning as perfect tenses or past tenses.
We often use perfect infinitives to talk about ‘unreal’ past events.
Form: (to) be + past participle
Passive infinitives have the same kind of meaning as other passive forms.
Perfect progressive infinitive
Form: (to) have been + present participle
Perfect passive infinitive
Form: (to) + have been + past participle
Perfect passive infinitives are also common.
