Morphology

diametrical = diameter (semi-transparent) = diameter + ical

The word is formed from 'diameter' plus an adjectival suffix, but the stem has a learned/orthographic shape that is not fully predictable for average learners.

Etymology

Diametrical comes from the Greek parts dia- ('through' or 'across') and metron ('measure'), the same root as diameter, so it literally refers to a line or measurement that goes 'across the center'. So diametrical is used for things that are measured across a diameter or that go straight through a circle or object.
