Morphology

semiclosed = closed (transparent) = semi + close

The meaning is directly compositional: 'semi-' means partly and 'closed' means not open.

Etymology

Semiclosed comes from the parts semi- and closed, where semi- means 'half' or 'partly' (as in semicircle) and closed means 'shut'. So a semiclosed interval in math is like a line with a solid dot at one end and an open circle at the other, including one end but not the other.
