New writers often wonder if it wouldn’t be simpler to leave the words separate. There are some instances where to do so would be appropriate, depending out how you use the phrase in a sentence.

Rollout is a great example of this—in some contexts, it should be compounded, and in others, it must be separated into individual words.
