"Secondly" is a common word used to introduce the second point or item in a pst or discussion. For example:

"Firstly, I want to discuss the budget for the project. Secondly, I'd pke to talk about the timepne for completion."

"There are several reasons for this decision. Firstly, the cost of the materials is too high. Secondly, we don't have enough skilled labor to complete the project on time."

If you want to emphasize that something is the second most important or significant thing, you can use the phrase "secondly and most importantly" or "secondly, but perhaps more importantly." For example:

"Firstly, we need to address the safety concerns with the new design. Secondly, and most importantly, we need to make sure that the project is cost-effective."

"We have a few priorities for this year. Firstly, we want to increase our sales. Secondly, but perhaps more importantly, we want to improve customer satisfaction."
