I have often seen writers pause mid-sentence, unsure whether second or secondly is the correct choice.
This confusion is common because both words exist, both sound natural, and both appear in formal and informal writing.
People search for second or secondly when writing essays, emails, lists, or speeches and want to sound correct and professional.
The problem is not spelling but usage. Using the wrong form can make writing feel awkward or outdated.
This article clears that confusion with a quick answer, clear rules, real examples, and practical advice so you always know which word fits your sentence best.
Second or Secondly: Quick Answer
Second and secondly are both correct, but they are not always interchangeable.
- Second is the modern, preferred choice in most writing.
- Secondly is grammatically correct but sounds more formal and is now less common.
Examples:
- ✅ First, we reviewed the budget. Second, we approved the plan.
- ✅ Firstly, the policy affects costs. Secondly, it impacts staff morale.
In most cases, second is clearer, shorter, and more natural.
The Origin of Second or Secondly
The word second comes from the Latin secundus, meaning “following” or “next in order.” It has been used in English for centuries as both a number and a sequence marker.
Secondly developed later by adding -ly, a suffix used to form adverbs. In older English, writers preferred adverbial forms like firstly, secondly, thirdly. Over time, English style shifted toward simplicity.
Modern usage favors first, second, third instead of longer adverbs. This is why secondly still exists but feels slightly old-fashioned today.
British English vs American English Usage
There is no spelling difference between British and American English here. The difference is about style, not correctness.
| Variety of English | Preferred Usage | Example |
| American English | Second | Second, we need more data. |
| British English | Second (modern) | Second, the issue remains unresolved. |
| Formal British writing (older style) | Secondly | Secondly, the committee agreed. |
Both regions now prefer second in most contexts.
Which One Should You Use?
Your choice depends on your audience and tone.
- US audience: Use second
- UK/Commonwealth audience: Use second
- Academic or very formal writing: Either is correct, but second is still safer
- Global audience: Use second for clarity and simplicity
If you want your writing to sound modern, natural, and professional, second is the best choice.
