The word 透露 is formed by combining two characters, each contributing to an overall metaphorical image. 透 originally depicts movement (辶) through or past something, suggesting penetration or passing through, like light through a shutter. 露 depicts moisture (雨) on a path (路), evoking something hidden becoming visible, like dew revealed at dawn. Together, they create a coherent concept: to allow something concealed (like news or a secret) to pass through a barrier and become visible or known, much like light leaking through or dew appearing.
