Requester vs Requestor: What’s the Difference?

Requester

The term “requester” is more commonly used in everyday English. It refers to anyone who makes a request, typically in a general or formal context. This word is the more commonly accepted spelling across a variety of settings, including business, customer service, and general communication.

Requestor

“Requestor,” on the other hand, is more specific and tends to be used in technical, legal, or formal contexts. It often appears in fields like IT, law, and procurement, where it refers to an individual or entity who initiates a formal request, such as a “requestor” of services or information.

What Does “Requester” Mean?

It’s a more universally accepted term, suitable for both formal and informal uses. From customer service requests to HR documents, you will often see “requester” used when referring to someone initiating an inquiry or petition.

Examples of “Requester” in a Sentence

• “The requester submitted their application through the online portal.”
• “The requester was informed that their complaint would be addressed within 24 hours.”
• “As a requester of services, you need to fill out the appropriate forms.”

In everyday writing and communication, especially when dealing with requests for services, resources, or information, “requester” is the preferred spelling.

What Does “Requestor” Mean?

In fields such as law, procurement, and database management, the word “requestor” might be the standard term used to describe the person or entity making a formal request. For instance, in software development or API documentation, the term “requestor” can refer to the system or user initiating a request for data.

Examples of “Requestor” in Context

• “The requestor of the patent must submit additional documentation before approval.”
• “As the requestor of the IT service, please follow the outlined steps.”
• “The requestor should ensure that all required fields are filled out properly before submitting the form.”

While “requestor” is technically correct, it is often reserved for more formal or technical contexts where precision and formality are necessary.

Word Origins: Where Did “Requester” and “Requestor” Come From?

The history of both words traces back to the root word “request,” which originates from the Latin word requaerere, meaning “to ask for” or “to seek.” The suffixes “-er” and “-or” are commonly used in English to create agent nouns, which denote the person performing an action.

• “Requester” uses the “-er” suffix, which is more widely used to form agent nouns for general terms in English (e.g., writer, teacher, worker).
• “Requestor” uses the “-or” suffix, which is traditionally reserved for more formal or technical roles (e.g., director, creator, contractor).

Over time, both spellings have emerged in English, but “requester” became more common in everyday speech, while “requestor” found its niche in legal and technical writing.

Google Ngram Trend

If you look at historical usage trends (via Google Ngram), you’ll see that “requester” has been more widely used since the 19th century, while “requestor” emerged later and is seen more often in legal and IT-related texts.
