Inmost cases the differentiation between the gerund and the participle does not present any difficulty.
Unlike the participle the gerund may be preceded by a preposition, it may be modifiett by a noun in the possessive case or by "a possessive pronoun; it can be used in the function of a subject, object, and predicative. In the function of an attribute and of an adverbial modifier both the gerund and the participle may be used, but the gerund in these functions is always preceded by a preposition.
There are cases, however, when the differentiation between the gerund and the participle presents some difficulty; for instance, it is not always easy to distinguish between a gerund as part of a compound noun and a participle used as an attribute to a noun. One should bear in mind that if we have a gerund as part of a compound noun, the person or thing denoted by the noun does not
perform the action expressed by the mg-form: e. g. a dancing-hall (a hall for dancing), a cooking-stove (a stove for cooking), walking shoes, a writing-table, etc.
If we have a participle used as an attribute the person denoted by the noun performs the action expressed by the ing-form: e. g. a dancing girl (a girl who dances), a singing child, etc.
However, there are cases which admit of two interpretations; for example a sewing machine may be understood in two ways: a machine for sewing and a machine which sews; a hunting dog may be a dog for hunting and a dog that hunts.
The gerund and verbal noun.
The gerund should not be confused with the verbal noun, which has the same suffix -ing. The main points of difference between the gerund and the verbal noun are as follows:
1. Like all the verbals the gerund has a double character — nom inal and verbal.
2. The gerund is not used with an article.
3. The gerund has no plural form.
4. The gerund of a transitive verb takes a direct object. He received more and more letters, so many that he had given up reading them. (Priestley)
5. The gerund may be modified by an adverb.
Drinking,even temperately, was
a sin. (Dreiser)
The verbal noun has only a nominal character.
The verbal noun may be used with an article.
Themaking of a new humanity cannot be the privilege of a handful of bureaucrats. (Fox)
I want you to give my hair agood brushing.(Hardy)
The verbal noun, may be used in the plural.
Our likingsare regulated by our circumstances. (Ch. Bronte)
A verbal noun cannot take a direct object; it takes a prepositional object with the preposition of.
Meanwhile Gwendolen was rallying her nerves to the reading of the paper. (Eliot)
The verbal noun may be modified by an adjective.
He (Tom) took a good scoldingabout clodding Sid. (Twain )
THE INFINITIVE
§ 26. The infinitive developed from the verbal noun, which in course of time became verbalized, retaining at the same time some of its nominal properties. Thus in Modern English the infinitive, like the participle and the gerund, has a double nature, nominal and verbal.
1. The nominal character of the infinitive is manifested in its syntactic functions. The infinitive can be used:
(a) as the subjectof a sentence.
To go on like thiswas dangerous. (Galsworthy)
(b) as a predicative.
Her plan was now to drive to Bath during the night.(Hardy)
(c) as an object.
I have never learnt to read or write.(Collins)
2. The verbal characteristics of the infinitive are as follows:
(a) the infinitive of transitive verbs can take a direct object.
He ... began to feel some curiosity ... (Eliot)
(b) the infinitive can be modified by an adverb. I cannot write so quickly.
(c) the infinitive has tense and aspect distinctions; the infinitive of transitive verbs has also voice distinctions.
In Modern English the infinitive has the following forms:
Active
Passive
Indefinite Continuous Perfect Perfect Continuous
to write to be writing to have written to have been writing
