Morphology
Triassic = tri (opaque) = tri + assic
The formation and meaning of 'Triassic' is not transparent to learners; it is a specialized geological term whose meaning cannot be derived from 'tri' alone.
Etymology
Triassic comes from the root tri- meaning 'three', the same 'tri' you see in triangle or tricycle. Scientists called a set of rocks the Trias because they have three main layers, so when we say something is 'Triassic' we mean it comes from the time about 252 to 201 million years ago when early dinosaurs and marine reptiles first showed up.
