Origins of the Words “Requester” vs. “Requestor”

Both requester and requestor originate from the verb “to request,” which comes from the Latin term requaerere, meaning to ask or seek.

The word “requester” originates from the Latin term requaerere, meaning to ask or seek. As the language evolved, requaerere transitioned into Old French as requeste, embodying the essence of inquiry and reflecting humanity’s natural tendency to seek information and assistance. Over time, it entered Middle English, solidifying its place in the language as the widely accepted term for someone who makes a request.

The English language embraced the term requeste and appended the suffix -er, giving rise to "requester" a word that distinctly signifies someone who makes a request.

“Requestor” also originates from requaerere and retains the Latin agent noun suffix -or, which denotes someone who performs an action. While it shares the same fundamental meaning as “requester,” over time, it has evolved into a more specialized term, primarily used in legal, financial, and technical contexts, where it is often the preferred choice.

Note:

The suffix "-er" in "requester" reflects the Germanic influence on English, whereas the "-or" in "requestor" stems from Latin roots. This dual linguistic heritage plays a key role in the ongoing debate over their preferred usage.
