Definition
A property of a material that allows light to pass through it, but in a diffused way so that objects on the other side cannot be seen clearly.
Plain English
Light gets through the material, but you can't see clearly through it. Think of frosted glass: bright on the other side, but the shapes behind it are blurry.
Context Anchor
Seen in descriptions of aircraft materials such as light covers, panels, or inspection windows.
Derivation
From Latin trans- ('through') and lucere ('to shine'). Literally 'shining through.' That captures the idea exactly: light shines through, but the view does not.
Why Pilots Care
Aircraft components such as inspection panels and light covers often use translucent materials to allow controlled illumination or visual checks without exposing internals fully.
Analogy
Frosted glass is translucent: a room may look bright through it, but you cannot clearly see the objects on the other side.
Intuition Check
Translucent does not mean the same thing as transparent. Transparent means you can see clearly through it; translucent means light passes through, but the view is blurred or blocked.
Example Sentence 1
The translucent cover over the compass card lets the internal light illuminate the numbers at night.
Example Sentence 2
Translucent wing root fairings let the preflight light reach internal structure without direct exposure.
