tachistoscope singular

Morphology

tachistoscope = scope (opaque) = tachisto + scope

The word is built from a technical combining form meaning 'rapid' plus 'scope', but the full scientific meaning is not readily recoverable for an average learner.

Etymology

The word tachistoscope comes from Greek parts tachy- meaning 'fast' and -scope meaning 'to look', the same scope you see in telescope and microscope. So a tachistoscope is like a 'fast-looking' device that shows images for a very short time to help researchers study how people see.
