Simple Origin and Background

Both words come from the verb request, which means to ask for something politely or formally.

English often creates nouns by adding endings such as:

• -er
• -or

For example:

Verb	Person
teach	teacher
work	worker
act	actor
inspect	inspector

Over time, English developed different endings for people who perform an action.

When the verb is request, two forms appeared:

• requester
• requestor

Since both follow English word building patterns, both became accepted spellings.

However, everyday English gradually began using requester more often, making it the preferred choice in most situations.
