Morphology

trichotomy = dichotomy (semi-transparent) = tri + chotomy

The prefix 'tri-' clearly indicates three, but 'chotomy' is not a standalone English word, making the full meaning less accessible.

Etymology

Trichotomy comes from two parts: tri- meaning 'three', like in triangle or trio, and -chotomy meaning 'cutting' or 'division', like in dichotomy or anatomy. So a trichotomy is a 'cutting into three' and means a division into three parts.
