Reserver

Reserver is a noun derived from the verb reserve. In English, it is an uncommon agent noun meaning one who reserves something or one who makes reservations. In practice, the term is rarely used in contemporary English, and more common expressions such as guest, customer, booking agent, or reservations clerk are preferred depending on context. Historically, reserver could refer to a person who sets aside resources or earmarks funds, time, or space for future use, but such usage is now largely supplanted by other terms.

Etymology: Reserver comes from the verb reserve, which via Old French reserver and Latin reservare gave rise to English forms. The agent noun suffix -er yields reserver, but this formation is infrequent in modern usage.

Distinctions: Reserver is distinct from reservist, a military member serving in the reserve; from reservation, the act of booking or the clause in a contract; and from reserve, the thing set aside or the noun meaning the stored supply. In most contexts, the intended meaning is clear from surrounding words without the noun reserver.

Usage notes: Given its rarity, many writers choose more precise terms such as booking agent, reservations clerk, one who makes reservations, or simply guest depending on the situation. The term may appear in historical texts or in discussions of language and grammar as an example of an agent noun formed with the suffix -er from reserve.
