Requester or Requestor – Quick Answer

- Requestor is mainly used in legal and formal contexts, especially in American English.

The Origin of Requester or Requestor
The word comes from request, which comes from Latin requirere, meaning “to ask” or “to seek.”
In English, people who perform an action often end with -er or -or:
- worker
- actor

Both endings are correct in English. Over time, -er became more common in modern usage. However, -or stayed popular in legal, official, and technical language. That is why requestor still appears in contracts and laws, while requester dominates general writing.
