ESSENTIAL GRAMMAR SKILLS
Lesson 3: Parallelism
The Law of Parallelism
When you compare or list items in a sentence, the items should have the same grammatical form. That is, if the first item is an infinitive (or a gerund, or an adjective, etc.), the other item(s) should be, too.
The three items have different forms. The sentence sounds best if they are all gerunds.
The first item is an infinitive, but the second is a gerund. Make them the same form.
In all constructions like the following, the words or phrases that replace A and B must be parallel.
Infinitives vs. Gerunds
Infinitives are verblike phrases like to run, to see, and to think, which usually act as nouns.
Gerunds are also verblike words, like running, seeing, and thinking, and they also often act as nouns.
What kind of word is pizza? Obviously a noun. But notice that in the sentences above, to swim (infinitive) and swimming (gerund) are playing the same role as pizza did in the first sentence. So they must be nouns too!
Usually, gerunds and infinitives are interchangeable. But in some situations, one is preferable to the other.
• The gerund often indicates a general class of activity, while the infinitive indicates a specific activity.
• The infinitive indicates a stronger connection between subject and action than does the gerund.
Does Cara simply like to watch dancing, or does she herself do the dancing?
This sentence clearly indicates that Cara herself dances.
• The infinitive often indicates purpose or intention better than does the gerund.
