What does semitransparent mean?
Semitransparent means partly transparent: it describes a material or surface through which some light passes, while preventing a completely clear view of what is behind it. The term is common in descriptions of plastics, films, glass, paper, fabrics, and biological tissues. It can also be used figuratively to suggest that a feeling, intention, or meaning is visible but not fully disclosed. In everyday use, semitransparent conveys a middle condition between transparency and complete opacity. The standard spelling is generally semitransparent, although semi-transparent is also widely accepted, especially in technical writing. The word is useful when the degree of visibility matters: unlike transparent, it does not imply that the background can be seen clearly, and unlike opaque, it does not imply that light is entirely blocked.
adjectiveAllowing some light to pass through, but not enough to make what is behind it fully visible. It may also describe something that is partly opaque or only partly discernible.
- Allowing some light to pass through without being completely clear.

"Her expression was semitransparent: she tried to hide her embarrassment, but not very successfully."
The word transparent comes from a Latin verb meaning “to see through,” so a semitransparent object is literally one you can see through, but only partly.

Where does semitransparent come from?
The word combines the English prefix semi-, meaning “half” or “partly,” with transparent. Transparent comes from Latin transparens, a present participle meaning “showing through,” derived from transparere, formed from trans-, meaning “across” or “through,” and parere, meaning “to appear.” Related words include transparency, apparent, and parent, all ultimately connected with the Latin root associated with appearing or being seen.

Easily confused with semitransparent
