What Do “Requester” and “Requestor” Mean?

The requester meaning and requestor meaning are nearly identical. They’re both agent nouns words formed by adding a suffix to a verb to indicate a person who performs that action. In this case, “request” becomes either “requester” or “requestor.” While interchangeable in casual conversation, the preferred term can shift depending on the domain legal, technical, or business terminology.

Requester vs Requestor: Spelling and Usage Explained

Here’s where it gets tricky: the words are often used in different fields, and “requester vs requestor spelling” isn’t always about correctness it’s about context.

DomainPreferred TermExample Usage

Legal contextRequestor“The requestor filed a motion with the court.”
Technical writingRequester“The requester initiated the API call.”
Government useRequestor“The FOIA requestor appealed the decision.”

Tip: In most day-to-day and formal writing terms, use requester unless you’re working in legal or government settings.

Word Origins: How Did We Get Two Spellings?

Both words stem from the Latin root requaerere, meaning “to seek” or “to ask.” From there, English adopted the base “request” and eventually evolved it into two forms using agent noun suffixes: “-er” and “-or.”

  • “-er” suffix is common in British and American English (e.g., teacher, runner, requester).
  • “-or” suffix often appears in legal or classical terms (e.g., executor, requestor).

This explains why requestor shows up more in specialized terminology, while requester is the dominant form in everyday communication.
