sandbox
C1Informal, Technical
Definition
Meaning
A shallow container filled with sand for children to play in.
1. In computing: a controlled, isolated environment for testing software or running untrusted code without affecting the main system. 2. More broadly: any safe, contained space for experimentation or development without real-world consequences.
Linguistics
Semantic Notes
The computing sense is a metaphorical extension of the child's toy. Both meanings share the core concept of a bounded area for safe play/experimentation.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid calquing as 'песочный ящик' for the computing term; use 'песочница' (pesochnitsa) for both meanings. The direct translation 'ящик с песком' is unnatural.
Common Mistakes
- Using 'sandbox' for a sandpit in formal British English. Confusing 'sandbox mode' in games (open-world) with the security 'sandbox' (isolated).
