When something is semivisible, it means that it can only be partially seen or is somewhat visible. There are several synonyms for the word semivisible, including translucent, filmy, hazy, cloudy, obscure, indistinct, faint, and blurry. These words describe something that is not completely visible or is difficult to see clearly. For instance, a translucent curtain might allow some light to filter through, but it is not entirely transparent. Filmy and hazy both suggest a foggy or misty quality, while obscure and indistinct imply that something is not clear or sharply defined. Faint and blurry suggest that something is not well-defined or focused.
