The Origin of Sempai or Senpai
The word senpai comes from Japanese 先輩 and is written as せんぱい in hiragana. It describes someone who entered a school, workplace, club, or group before another person.
The word is not limited to age. A senpai is usually someone who has more experience or seniority because they joined earlier.
For example, in a school:
- A second-year student can be a senpai to a first-year student.
- The first-year student is called a kohai.
- A student can become a senpai when they move into a higher year.
The word is also used in workplaces, sports teams, martial arts, and other groups.
Why does “sempai” exist?
The difference comes mainly from pronunciation. In Japanese, the word is written せんぱい, which is romanized as senpai. However, the n sound before p can sound closer to an m sound when spoken. This makes sempai feel natural to some English speakers.
That is why both spellings can be found in English.
British English vs American English Spelling
There is no major British-versus-American spelling difference for this word.
British English and American English generally use senpai. The spelling does not change in the way some words do, such as colour/color or centre/center.

| Alternative spelling | sempai | sempai |
| Meaning | Senior or experienced member | Senior or experienced member |
