Second or Secondly: What Is the Difference? 2026

Comparison Table

The Origin of Second and Secondly

“Second” comes from older forms of French and Latin. The Latin word secundus meant “following” or “next.” English later used “second” to show order.

“Secondly” comes from “second” plus the ending “-ly.” This ending helps form adverbs. It turns the word into a form used to introduce a point.

The two words share the same history. Their modern uses have grown from the idea of coming next in a series.

Which One Should You Use?

For readers around the world, either form is easy to understand. The best choice is the one that makes your writing clear. If you start with “first,” you can continue with “second” and “third.” If you start with “firstly,” you can use “secondly” and “thirdly.”

Common Mistakes

Mistake 1: Saying Secondly Is Always Wrong

Incorrect claim: “Secondly” is never correct.

Correction: “Secondly” is accepted when introducing the second point.

Example: Firstly, we need a plan. Secondly, we need time.

Mistake 2: Mixing Forms Without a Reason

You can mix forms when needed. However, a matching style can make a list easier to follow.
