Etymology

The word "referral" emerged in the early 20th century, derived from the verb "refer," which traces back to Latin referre. The prefix re- (back) and root ferre (to carry) combine to imply "carrying back" or "redirecting." Over time, "refer" evolved to mean directing someone to another person or resource, and the suffix -al formalized it as a noun describing the act or result of referring.
