Split infinitives, To Split or Not to Split Infinitives, Examples & Exercises

What is a Split Infinitive?
An infinitive is said to be “split” when a word (often an adverb or phrase) comes between the “to” of the infinitive and the root of the verb.
To Split or Not to Split Infinitives
The argument against split infinitives is that the infinitive is a single unit and, therefore, should not be divided. As many people feel that the infinitive verb should follow the infinitive marker directly. Thus it is recommended that the adverb should be placed either before the infinitive marker or after the verb. However, there in nothing inherently wrong with split infinitive, and it is sometimes best or only way of avoiding confusion.
For example:
Aslam refuses to actively try to make them change their ways of life.
She tries to absolutely reject this plan.
He decides to boldly go where no man has gone before.
Generally it is wrong to separate an infinitive from the particle “to” by the intrusion of some modifying words.

You are to kindly note this. (Incorrect)
