§ 104. This adverbial answers the identifying questions what for? for what purpose? It is most frequently expressed by an infinitive, an infinitive phrase or complex.

Jane has come to help us.

I've repeated my words for you to remember them.

The meaning of purpose may be emphasized by the composite prepositions in order or so as, which are never used before an infinitive complex.

We must go early in order not to be late. We hurried so as not to be late.

The adverbial of purpose may also be expressed by a noun, a prepositional phrase, nominal or gerundial, introduced by the preposition for.

We reserved this table for lunch.

We use the thermometer for measuring temperature.

After the imperative of the verbs to go and to come another imperative is preferable to the infinitive, as in:

Go and help him. (Not *Go to help him.)

Come and wash up. (Not *Come to wash up.)

The use is optional for the verb to see.

Come to see me, or Come and see me.

Go to see him, or Go and see him.

The adverbial of result (consequence)

§ 105. The adverbial of result has no identifying questions. It refers to an adjective, a noun with qualitative meaning, or an adverb accompanied by an adverb of degree, such as too, enough, sufficiently, so... (as). The adverbial of result is expressed by an infinitive, an infinitive phrase, or complex.

It is too cold to go out.

The lecturer spoke slowly enough for us to take down everything he said.

He was fool enough to believe it.

John was so fortunate as to get the first prize.

He felt he was enough of a citizen of the world not to mind it.

The adverbial of degree too signals a negative result, enough suggests the necessary amount of quality to perform the action. The correlative phrase so... as implies a realized action, unlike the phrase so as before adverbials of purpose suggesting a hypothetical event. Compare these sentences:

John was so fortunate as to get the first prize (and he got it) – result.

John trained hours so as to get the first prize for boating (we do not know whether he has got it or not) - purpose.

The adverbial of condition

§ 106. The identifying questions are in what case? or on what condition? The adverbial of condition is generally expressed by a noun or a pronoun, or by a prepositional phrase (nominal or sometimes gerundial) with the prepositions but for, except for, without.

But for you I wouldn't be here at all.

Except for the sound of his breathing I wouldn't have known he was there.

Without faith there can be no cure.

This adverbial is sometimes expressed by a participle or an adjective with the conjunctions if or unless.

Jane won't sing unless asked to.

We'll come earlier if necessary.

Less frequently it is an infinitive or a participle.

I would have done better to have followed my first thought.

Skillfully managed, conversation with him might prove amusing.

The adverbial of concession

§ 107. This adverbial expresses some idea that contradicts what is stated in the modified part of the sentence. Thus in its meaning it is opposite to the adverbial of reason. The identifying question is in spite of what?

The adverbial of concession is expressed by a prepositional phrase introduced by in spite of, despite, for all, with all and phrases introduced by the conjunction though.

In spite of his anger John listened to me attentively.

Cleary, for all his reputation, was already out of date.

With all his faults, I like him.

Though a bad painter, he had a delicate feeling for art.
