Expert writing Tips
Best practice
Use "is not empty" to clearly indicate that a space, field, or set contains content and should be considered in your logic or process.
Common error
Avoid using "is not empty" when you really mean to convey that something exists. "Exists" confirms presence, while "is not empty" focuses on the absence of void. For example, it's better to say "the file exists" rather than "the file is not empty" if your primary concern is the file's presence.

Ludwig's WRAP-UP
The phrase "is not empty" is a grammatically correct and commonly used expression to indicate the presence of content or data within a given context. As Ludwig AI confirms, its application spans across various domains, including science, academia, and news media. It serves the crucial function of asserting that something contains elements, thus being the contrary of void. While alternatives like "contains content" or "has data" exist, "is not empty" provides a specific emphasis on the absence of emptiness, frequently utilized in conditional checks and data validation. It is important to note, however, to favor simpler options when possible like using "exists" instead. The frequency of its occurrence designates it as a very common phrase, solidifying its relevance in both formal and neutral registers.

What's a formal alternative to "is not empty"?

What does it mean if a data structure "is not empty"?

When should I use "is not empty" instead of "contains data"?
