Morphology

goniometer = meter (transparent) = gonio + meter

The word is a transparent classical combining-form construction built from gonio- meaning angle and meter meaning measuring device.

Etymology

The word goniometer comes from Greek parts goni 'angle' and -meter 'measure'. So, it is literally an 'angle measurer', like a school protractor or a thermometer, and therapists or scientists use a goniometer to measure angles in joints or crystals.
