Etymology
The word 'sandbox' is a transparent compound formed from two Old English roots. 'Sand' has ancient origins in Proto-Indo-European, referring to the granular substance. 'Box' entered Old English via Latin from a Greek term for a container made of boxwood. The compound literally means "a box for sand." Its original, concrete meaning refers to a physical play area for children. In the late 20th century, this concept of a contained, safe, and isolated play space was metaphorically extended to computing, giving rise to the term's second meaning for a secure, isolated software testing environment.
