MTEL Communication Literacy Skills : Writing Practice Test

A split infinitive occurs when an adverb or other word is placed between "to" and the base form of the verb, creating a separation in the infinitive construction. For example, in the phrase "to boldly go," the word "boldly" splits the infinitive "to go." This structure can sometimes enhance clarity or add emphasis to the verb. The other options describe different grammatical concepts. Lacking a subject does not relate specifically to infinitives, nor does using an infinitive in the past tense or for showing possession. Therefore, understanding the significance of the structure in a split infinitive is essential for proper grammar usage, especially in writing.
