Etymology
The word 'inbox' is a transparent compound formed in modern English from the native preposition 'in' and the noun 'box'. The term 'box' itself has a long history, entering Old English from Latin via Greek, originally referring to a small container made of boxwood. The concept of an 'inbox' as a designated receptacle for incoming items emerged in office contexts in the early 20th century. Its meaning was seamlessly extended with digital technology to denote the virtual folder for receiving electronic mail, perfectly preserving the literal logic of a container for items coming 'in'.
