semiconductor singular

Morphology

semiconductor = conductor (transparent) = semi + conduct + or

Adding semi- to conductor produces the standard meaning of a material that conducts electricity only partly or under certain conditions.

Etymology

Semiconductor breaks into semi- meaning 'half' and conductor meaning 'one that leads'. So a semiconductor is a material that 'partly conducts' electricity — it lets some electricity through but not as much as a full conductor.
