Morphology

trigonometric = trigonometry (semi-transparent) = trigon + metric

The base 'trigonometry' is clear, but the suffix '-ic' indicates a relation that may not be immediately obvious to all learners.

Etymology

The word trigonometric comes from Greek parts tri- 'three' and gonia 'angle', so trigon- means 'triangle', and the ending -metric comes from a word meaning 'measure', like in meter. So trigonometric is about 'measuring triangles', which is why it deals with the angles and sides of triangles.
