The Origin of First or Firstly
The word “first” comes from Old English fyrst, meaning “before all others.” It has been used for centuries in both speech and writing.
The word “firstly” was formed later by adding -ly, a suffix used to create adverbs (like quickly, slowly).
In older English, writers often used:
- firstly
- secondly
- thirdly
But over time, many style guides started to prefer:
- first
- second
- third
Why? Because “first” already works as both an adjective and an adverb. So adding “-ly” is not always needed.
British English vs American English Spelling
There is no spelling difference between British and American English. However, there is a style difference.
- American English: prefers “first”
- British English: accepts both, but “first” is still more common
