tricorder

The word "tricorder" is a Modern English neologism created for the star trek franchise. It is a portmanteau constructed from the elements "tri-" and "cord", with the addition of the common English instrumental suffix "-er". The "tri-" prefix suggests the device's three primary functions (sensing, computing, and recording), while "cord" is a clipped form of "recorder". The logic of the name thus implies an instrument that records three types of data. Its formation follows a pattern of English technical terminology, blending classical roots with a productive suffix to create a plausible and memorable name for a futuristic tool.
