Infinitive
The Infinitive is always used with the particle to and usually expresses an action denoted by the predicate verb.
To visit her is always a pleasure.
Sentences with the infinitive as subject have certain structures:
The infinitive may be used in declarative sentences.
The infinitive is placed at the head of the sentence.
It is expressed by a noun, adjective qualifying the action denoted by the infinitive.
The infinitive as predicative:
The infinitive in this action has appositive meaning i.e. it explains the meaning of the subject of the sentence.
All I want to do is to help you.
The Infinitive as Object:
The Infinitive may be used as an object to a verb.
We find it after the verbs: to agree, to ask, to care, to begin, to like, to hate, to swear, to offer, to expect and others.
Mark continued to visit Jack in hospital.
In addition to the verbs mentioned above the infinitive as object is used after the modal verbs can afford and can bear in the negative and interrogative forms.
Some say we cannot afford to do it.
The Infinitive may be used as an object to an adjective. It is used after various kinds of adjectives- able, afraid, certain, anxious ,lucky, eager and others.
He is still very anxious to see her.
Occasionally a for0phrase is used to show the subject of the infinitive.
He was eager for me to start on my new job.
The infinitive as object may be part of a phrase introduced by the conjunction
Whether, what, how ,how long where
I did not at all know what to say.
The infinitive may serve as object in a special sentence pattern with a formal it as subject. The most commonly occurring verbs after which the infinitive is used in this function:
To amaze, to worry, to trouble, to excite, to interest, to shock, to please and others.

The infinitive as Subjective Predicative.
The infinitive as Subjective Predicative is always preceded by to. It is lexically dependent – it follows a number of transitive verbs used in Passive.
These verbs are: to advise, to believe, to report, to aloe, to leave, to find, to invite, to require and others.
I have been advised to rest.
Infinitive as Adverbial Modifier
The infinitive may serve as adverbial modifier to a verb. In this function it is used to express purpose, comparison, condition.
Purpose- infinitive is used with to
I come in to see if I could help you pack.
The infinitive of purpose may occasionally be preceded by the modifiers
In order and so as which emphasize the idea of purpose/
I was silent for a moment in order to give greater force to my next remark.
The infinitive with to may serve as an adverbial modifier of condition. In this
case it expresses a condition under which the action of the predicate verb can be
realized.
To hear him talk you would think he was a celebrity.
The infinitive as modifier of consequence is used with the to we find a peculiar sentence pattern, the first part of which is, had only, had but to…
