Requestor or Requester – Quick Answer
Quick Answer:
Requester is the standard and widely accepted spelling.
Requestor is a less common variant used in specific fields like law and computer systems.
Examples:
- The requester asked for more time.
- In some legal forms, you may see “requestor information”.
In most writing, especially general English, requester is correct.
The Origin of Requestor or Requester
The word comes from the verb request + the agent suffix –er/or.
In English, both –er and –or form nouns that mean “one who does something,” like:
- Runner (one who runs)
- Creator (one who creates)
The suffix –er is more common in general English, while –or comes from older Latin forms and appears in some technical or legal terms. That’s why requester became the dominant version in modern writing.
Over time, English developed two paths for agent words:
- –er for everyday use
- –or for formal or legal contexts (e.g., executor, debtor)
So both versions exist, but requester is more widely accepted.
