When to Use Continual vs Continuous
Accuracy is an important part of scientific and medical writing. But accuracy does not only apply to technical terms and complex concepts. It also applies to common words and phrases. By using the most accurate words throughout your text, you can ensure your writing is clear, consistent, and easy for readers to understand.
One common word that I often see misused is the term continuous. Authors will use this term as a synonym for continual. Although these terms may seem similar, their definitions have important nuances that distinguish their meanings.
Definitions
Continual means to recur at regular and frequent intervals.
Continuous means to persist without pause or interruption.
