Half-seen is a term that implies something partially perceived, or not fully visible. There are several synonyms that can be used to describe this condition, including obscured, partially hidden, and semi-transparent. Other options might include faintly visible, shadowy, or indistinct. These words all suggest that something is present but not quite fully realized, perhaps obscured by shadows or distance. Half-seen can apply to physical objects, such as a figure in the mist, or abstract concepts, such as an idea that is only partly formed. Whatever the context, the term half-seen evokes a sense of uncertainty and ambiguity, leaving room for interpretation and imagination to fill in the gaps.
