Expert writing Tips
Best practice
Pair it with an abstract noun like 'shift', 'pattern' or 'feeling' to describe subtle changes in a situation
Common error
Avoid using "I've detected" to describe a choice or a plan you have made. It is strictly used for perceiving or discovering something that already exists, not for initiating an action. For example, use "I've decided to go" instead of "I've detected to go".
