A “split infinitive” occurs when an adverb or other word is inserted between the “to” and the base form of a verb in an infinitive phrase. The infinitive phrase is the base form of a verb preceded by the word “to,” such as “to run,” “to jump,” or “to study.”
Key Points about Split Infinitives:
- Structure of an Infinitive: An infinitive is a verb form that begins with the word “to,” followed by the base form of the verb.
Example: to run, to eat, to play
- Definition of Split Infinitive: A split infinitive occurs when another word, often an adverb, is placed between “to” and the base verb form in an infinitive phrase.
Example: to boldly go, to quickly finish
- Common Adverbs in Split Infinitives: Adverbs that commonly appear in split infinitives include “quickly,” “boldly,” “eagerly,” and “carefully.”
Example: She decided to carefully read the instructions.
- Controversy: The use of split infinitives has been debated in English grammar. Traditional grammar rules sometimes discourage split infinitives, but modern usage has become more accepting.
- Clarity and Emphasis: In some cases, using a split infinitive can enhance clarity or place emphasis on a particular part of the sentence.
Example: He promised to never lie again.
- Placement of Adverbs: Adverbs in split infinitives are typically placed before the base verb form.
Example: She decided to quickly finish the project.
- Usage in Formal Writing: While split infinitives are generally acceptable in modern English, writers may avoid them in formal or academic writing to adhere to traditional style preferences.
Conclusion
Understanding split infinitives and when to use or avoid them can contribute to effective and grammatically sound writing. While they are generally accepted in contemporary English, writers should consider the context and style of their writing when deciding whether to use split infinitives.
