IPA: /trænˈsluːsənsi/
KK: /trænsˈlusənsi/
The quality of allowing light to pass through but not detailed shapes or images.
The translucency of the frosted glass allows light to enter while maintaining privacy.
Translucency → It is formed from "trans-" (meaning across) and "lucere" (meaning to shine or give light). The word describes the quality of allowing light to pass through, but not clearly enough to see through completely.
Think of something that lets light pass 'across' ('trans-') while still being somewhat obscured — that's what translucency means.
No commonly confused words.
