Morphology

tetrachoric = choric (opaque) = tetra + choric

Although the word can be segmented into a classical prefix and a base adjective, the statistical meaning of the term is highly specialized and not predictable for an average learner from those parts.

Etymology

The word tetrachoric (the coefficient) combines tetra- ('four') with choric ('place' or 'box'), which points to the four cells of a two-by-two table; a good memory image is the four boxes of a yes-or-no chart. That's why the tetrachoric measures the strength of the link between two yes-or-no variables.
