Morphology

tetrachoric = tetra + chor + ic

The term is built from Greek combining forms (tetra- + chor-) plus the adjective suffix -ic and is a technical formation not readily interpretable by an average B1 learner.

Etymology

The word tetrachoric comes from tetra- ('four') plus choric (a part that suggests 'place' or 'box'), so a helpful way to remember it is to imagine the four boxes in a simple yes-or-no table. That's why tetrachoric describes things that relate to the connection between two yes-or-no measures.
