TRANSLUCENT

adj. transparent; partially clear, partly transparent; lucid; easily understandable; glowing

In optics, transparency is the material property of allowing light to pass through. In mineralogy, another term for this property is diaphaneity. The opposite property is opacity. Transparent materials are clear: they can be seen through. Translucent materials allow light to pass through them only diffusely: they cannot be seen through.
