Overview

As you navigate the sophisticated landscape of C2 English, mastering advanced verb structures and understanding agency becomes paramount. This chapter is your key to unlocking truly nuanced and precise expression, empowering you to communicate with the clarity and authority of a native speaker. We’re moving beyond basic sentence construction to explore how you can articulate complex timelines with effortless grace, seamlessly weaving past actions into your present narrative.
Imagine the power of naturally explaining an event that happened before another, or describing what you’ve arranged for someone else to do for you.
This mastery is crucial for any learner aiming for a C2 English grammar level, where precision and stylistic choice distinguish you. You’ll learn to brilliant command agency to get things done, not by doing them yourself, but by orchestrating. We'll delve into structures like the causative, the impersonal passive, and the vital role of perfect gerunds and infinitives in linking past to present.
We’ll also refine your understanding of passive gerunds and infinitives and even explore the sophisticated stylistic tool of splitting infinitives. By the end of this guide, you’ll not just understand these advanced verb structures and agency concepts; you’ll wield them with confidence, transforming your expression into truly C2-level English.

How This Grammar Works

At the heart of these advanced verb structures lies the ability to manipulate perspective, time, and responsibility in your communication. They allow you to add layers of meaning that simple verb forms cannot.
The Causative (have/get something done) is about agency – specifically, when someone else performs an action for you. You are the orchestrator, not the doer. For example, instead of
I fixed my leaky tap,
you might say,
I had my leaky tap fixed by a plumber,
or
I need to get my computer repaired.
This structure shifts focus to the result and the arrangement, perfect for professional or service-oriented contexts.
The Impersonal Passive (It is said that / He is said to) provides objectivity and often distance, especially useful in formal reporting or when you don't want to attribute information directly. It's a way of presenting general consensus or reported information.
It is believed that the company will announce new policies soon.
Or, to speak about an individual:
The CEO is understood to be negotiating the merger personally.
Notice how this often uses infinitives to complete the thought, which can then be combined with perfect infinitives for past actions:
He is said to have resigned last week.
This brings us to Perfect Gerunds and Infinitives (having done / to have done). These structures are crucial for showing an action completed *before* the main verb's action.
She regretted having spoken so harshly.
(First she spoke, then she regretted it).
Or,
He claims to have met the president.
(He claims now about a past meeting). They bring incredible clarity to complex timelines.
Similarly, Passive Gerunds & Infinitives (being done / to be done) maintain the focus on the recipient of the action, but with the added nuance of a gerund or infinitive form.
He dislikes being told what to do.
(Someone tells him).
The report needs to be completed by Friday.
(Someone completes the report).
These allow for professional C2-level precision, keeping the emphasis where it needs to be.
Finally, Splitting Infinitives (to boldly go) is a stylistic choice. While historically debated, it's now widely accepted, especially when it adds clarity, emphasis, or a more natural rhythm to your sentence. Placing an adverb between to and the base verb (e.g.,
to quickly understand
) can make your meaning sharper and less ambiguous.

Common Mistakes

Navigating these advanced structures can be tricky, but recognizing common pitfalls will help you achieve mastery.
  1. 1✗ Confusing causative subject with agent:
✗
I had fixed my hair at the salon yesterday.
(Implies you did it yourself after the arrangement)
✓
I had my hair fixed at the salon yesterday.
(Correctly shows someone else did the action for you.)
*Explanation:* The causative
have/get something done
uses the past participle after the object.
  1. 1✗ Incorrect perfect gerund/infinitive usage for simultaneous actions:
✗
He admitted to steal the money.
✓
He admitted to having stolen the money.
*Explanation:* The perfect infinitive
to have stolen
correctly indicates the stealing happened *before* the admission. If the action is concurrent or habitual, the simple form is used (e.g.,
He likes to steal candy
).
  1. 1✗ Overlooking the impersonal nature of the Impersonal Passive:
✗
The professor is said to be believed that the theory is correct.
✓
It is believed that the theory is correct.
OR
The professor is believed to think the theory is correct.
*Explanation:* The Impersonal Passive focuses on general belief (
It is said
) or attributes a belief to a specific person (
He is said to
). Avoid redundancy by mixing structures.

Quick FAQ

Q

Why are these structures considered C2-level English grammar?

These advanced verb structures and agency concepts are C2 because they demand a deep understanding of nuance, perspective, and precise temporal relationships. They allow for conciseness, formality, and the subtle shifting of focus, which are hallmarks of masterful communication, crucial for sophisticated C2 English grammar.

Q

Can I always split infinitives, or is it still considered wrong by some?

While traditionally some grammarians frowned upon it, splitting infinitives is now widely accepted, especially when it improves clarity, emphasis, or natural rhythm. For instance,

to better understand
is often clearer than
to understand better.
Use it judiciously as a stylistic tool, not merely as a habit.

Q

What’s the main difference between to have done and to do in a sentence?

The perfect infinitive

to have done
refers to an action that occurred *before* the main verb's action (e.g.,
She pretended to have finished her homework
). The simple infinitive
to do
refers to an action that is simultaneous with or after the main verb (e.g.,
She wants to finish her homework
).

Q

When should I use get something done versus have something done?

Both forms of the causative are generally interchangeable.

Get something done
often implies a bit more effort or persuasion on the part of the subject, or is slightly more informal, while
have something done
can feel a little more straightforward or formal.
I got my colleague to help me finish
(persuasion) vs.
I had my car serviced
(standard arrangement).

Cultural Context

Native English speakers use these patterns intuitively to convey precise meaning and tone. The impersonal passive and perfect gerunds/infinitives often appear in more formal contexts like academic writing, news reports, or professional communications, lending an objective or authoritative voice. The causative (
have/get something done
) is incredibly common in everyday speech and business to talk about services.
Splitting infinitives, though historically debated, is now common across all registers when it aids clarity or adds a modern, dynamic rhythm to speech or writing. Regional differences are minimal for these core grammatical structures.

The 'That' vs 'To' Rule

If you start with 'It', you MUST use 'that'. If you start with a person or thing, you MUST use 'to'.

The 'After' Shortcut

If you are confused by 'Having done', try replacing it with 'After doing'. If the meaning stays the same, 'Having done' is likely correct.

Avoid 'Someone'

Use the passive gerund to avoid saying 'someone'. Instead of 'I hate someone lying to me,' say 'I hate being lied to.' It sounds much more natural.

Yes, get is very common in spoken English. It's slightly more informal and often implies that the task was difficult to arrange.
The first is causative (someone else did it). The second is Past Perfect (you did it yourself before another past event).
You can! But 'People say' is informal. In academic or professional writing, using It is said or He is said to makes you sound more objective and authoritative.
They mean the same thing. 'It is said that' focuses on the whole idea, while 'He is said to' focuses on the person. The latter is considered slightly more advanced.
Yes, in most cases. Having finished means the same as After finishing. The perfect form just sounds more formal and emphasizes that the first action is totally complete.
