Expert writing Tips

Best practice

Avoid using "firstly subsequently" as it is redundant. Choose either "firstly" or "subsequently" depending on whether you want to introduce the initial point or refer to a following action. For example: "Firstly, consider the budget" or "Subsequently, review the timeline".

Common error

Don't combine adverbs that indicate sequence redundantly. Using both "firstly" and "subsequently" together creates unnecessary repetition. Choose the most appropriate adverb to clearly indicate the order of events without being repetitive.
