Expert writing Tips

Best practice

Pair the phrase with specific body parts, such as "my legs felt weak", to provide clearer imagery in narrative writing.

Common error

Avoid using "felt weakly" when you mean to describe the subject's internal state. In the sentence "I felt weak", the word "feel" acts as a linking verb, which requires an adjective. Use "weakly" only if you are describing the manner in which the action of feeling was performed (e.g., "he felt weakly for the light switch").
