The words "requestor" and "requester" both mean the same thing: someone who makes a request. However, "requester" is the more common and widely accepted spelling in both American and British English for general use and everyday communication. It is versatile and appropriate for most informal and formal contexts. "Requestor" tends to be less common and is often used in more technical, legal, or specialized contexts, such as computer programming, API documentation, or legal documents, where it carries a slightly more formal or domain-specific tone. In American English, "requestor" may occasionally appear in formal or technical settings, while British English generally favors "requester" regardless of context. In summary:
- Use "requester" for general, informal, and most formal writing as it is more common and widely recognized.
- Use "requestor" when writing for specialized, technical, or legal audiences where domain conventions might prefer this spelling.
This distinction is more about spelling convention and context rather than difference in meaning. Both refer to someone who asks for something or makes a request.
