Expert writing Tips
Best practice
Consider using stronger, more direct verbs like "observe", "find", or "discover" to make your writing more concise and impactful. For example, instead of "the changes are noticed to occur", try "the changes are observed to occur" or "the changes occur". This will often improve readability.
Common error
Avoid using "are noticed to" simply to avoid active voice. Over-reliance on passive constructions can make your writing seem weak and indirect. When possible, rephrase sentences to use active voice and stronger verbs. Instead of "mistakes are noticed to be made", try "people make mistakes".
