An infinitive is the base form of a verb with 'to,' while a split infinitive is when an adverb separates 'to' and the verb. Split infinitives can be used judiciously for clarity and natural flow in writing.
An infinitive is the basic form of a verb preceded by the word 'to,' serving as a noun, adjective, or adverb. For example, 'to run,' 'to jump,' 'to study' are infinitive forms. It can be used in various ways in a sentence.
A split infinitive occurs when an adverb is placed between 'to' and the verb in an infinitive form. While traditionally frowned upon in grammar, many professional writers disregard this rule for clearer and more natural expression.
However, there are cases where splitting the infinitive, like in Strunk and White's example 'I cannot bring myself to really like the fellow,' enhances clarity and avoids awkward constructions.
