The Origin of Requester or Requestor
The word comes from the verb request, which entered English from Old French and Latin many centuries ago. It means “to ask for something politely.”
English often creates nouns by adding endings like:
- -er
- -or
Both endings can mean “a person who does an action.”
Examples:
| Verb | Person |
| Teach | Teacher |
| Act | Actor |
| Visit | Visitor |
| Request | Requester / Requestor |
The spelling requester became more popular because English commonly adds -er to modern action verbs.
The spelling requestor survived in special fields like:
- law
- government paperwork
- computer systems
- procurement software
That is why both versions still exist today.
