Morphology

polygrapher = polygraph (transparent) = poly + graph + er

The word is formed by the productive agent suffix -er added to the base polygraph, so the meaning is straightforward.

Etymology

Polygrapher comes from Greek parts poly- 'many' and -graph 'to write', the same root you see in photograph or autograph. A polygraph machine makes several lines of recorded data about a person's body responses, so a polygrapher is the person who runs the machine and reads those recordings.
