mail-order

The term 'mail-order' is a modern compound noun and adjective formed from two distinct Old French/Latin roots. 'Mail' evolved from a term for a travelling bag to signify the system of transporting letters and parcels. 'Order' developed from the concept of a structured sequence into a commercial instruction. Their combination in the late 19th century logically describes the commercial process where a customer's purchase instruction ('order') is transmitted and fulfilled via the postal system ('mail'), bypassing traditional in-person retail. This lexical creation directly mirrors the technological and commercial innovation of the era, encapsulating a complete transactional method within its two constituent parts.
