Expert writing Tips
Best practice
When describing a state of poor health, consider the specific nuance you want to convey. "Feel really unwell" indicates a noticeable level of discomfort, but alternatives might better suit the situation (e.g. "feel very sick" for more intensity, or "feel under the weather" for something milder).
Common error
While "feel really unwell" is acceptable in general use, it might sound less professional in formal documents or academic papers. Opt for more precise and formal language like "experiencing a significant decline in health" or "demonstrating symptoms of illness".
