What is a split infinitive?

A split infinitive occurs when a word or group of words is placed between "to" and the verb in an infinitive form. This construction is notable because it modifies the verb with an adverb or other words, providing additional context or nuance to the action described. For instance, in the phrase "to boldly go," "boldly" splits the infinitive "to go."

This construction can spark debate among grammarians and writers regarding stylistic preferences, but it is widely accepted in contemporary English. The presence of additional words allows for more expressive or emphatic statements, enhancing clarity and impact in writing. Understanding this definition is essential for recognizing and effectively using split infinitives in your writing.
