The word 实验室 (shíyànshì), meaning "laboratory", is formed conceptually by combining three meaningful building blocks: 实 (shí), meaning "real" or "actual"; 验 (yàn), meaning "to test" or "to examine"; and 室 (shì), meaning "room" or "chamber". The core idea of "experiment" is first created by joining 实 and 验 to convey "actual testing" or "practical examination". This compound is then logically placed before 室, resulting in the complete concept of a dedicated physical space, a "room for actual testing", which perfectly encapsulates the function of a laboratory.
