Comprehensive Guide to Gerunds and Infinitives

Defining the Gerund and the Infinitive

In English grammar, a verbal is a word formed from a verb but functioning as a different part of speech. The two primary types of verbals often studied together are gerunds and infinitives. A gerund is constructed by taking the base form of a verb and adding the suffix $-ing$, resulting in the formula $\text{verb} + -ing$. While it looks like a continuous verb form, it functions as a noun within a sentence. On the other hand, an infinitive typically consists of the word "to" followed by the base form of a verb, represented by the formula $\text{to} + \text{verb}$.

Determining whether to use a gerund or an infinitive after a particular verb or adjective is a foundational aspect of English syntax. While some verbs only allow one or the other, or change meaning significantly based on the choice, others permit both forms with little to no impact on the overall message of the sentence.

Verbs Followed by Both Gerunds and Infinitives

There are specific instances where a speaker can choose between using a gerund or an infinitive without altering the core meaning of the statement. Even though we can use both forms in these contexts, the choice often depends on personal preference or regional dialect rather than a strict grammatical rule. Common verbs that fall into this category include "start," "begin," "continue," "like," "love," "hate," and "prefer."

For example, if one were to say, "It started raining," the meaning is identical to saying, "It started to rain." Both sentences communicate the initiation of precipitation at a specific point in time. Similarly, "I like swimming" and "I like to swim" convey the same general preference for the activity of swimming. In these cases, the gerund $\text{swimming}$ and the infinitive $\text{to swim}$ are interchangeable without causing confusion or changing the semantic intent of the speaker.

The Use of Infinitives After Adjectives

A common grammatical pattern involves placing an infinitive immediately after an adjective. This structure is frequently used to express an opinion, a feeling, or a judgment regarding an action. The typical construction for this pattern is $\text{adjective} + \text{to} + \text{verb}$. This allows the speaker to describe the quality of the action being performed or the reaction the speaker has toward that action.

Specific examples of this construct include phrases such as "hard to learn," "easy to understand," "happy to help," or "important to remember." In the sentence "It is difficult to master a new language," the adjective "difficult" is followed by the infinitive "to master." Here, the infinitive clarifies exactly what is being described as difficult. This pattern is essential for constructing complex sentences that evaluate experiences or provide descriptions of tasks and emotional states.

Questions & Discussion

Q: When we discuss verbs where the meaning doesn't change, are there any exceptions to the interchangeability of gerunds and infinitives?

A: While verbs like "start" or "begin" generally take both without a change in meaning, some nuance can exist. For instance, we tend to avoid using a gerund if the main verb is already in the continuous form. One would usually say "It is starting to rain" rather than "It is starting raining" to avoid the repetitive sound of two $-ing$ endings in a row. However, as noted, in the standard past or simple tenses, the meaning remains consistent whether you use the gerund or the infinitive.
