Partial transparency where light passes through but objects on the other side aren't clearly visible; a state between opaque and translucent.
From 'demi-' (half) plus 'translucence' (from Latin 'translucere' meaning to shine through). A modern coinage combining classical prefix with scientific terminology.
Demitranslucence is everywhere in nature—frosted glass, cloud cover, fish scales—and it's actually an evolutionary advantage because it hides identity while still allowing light through!
