Morphology

tetrachoric + correlation + coefficient

The overall meaning is directly derivable from the parts: 'tetrachoric' specifies the type of correlation (for binary/two-level variables), 'correlation' indicates a relationship between variables, and 'coefficient' denotes a numeric measure. Although the term is technical, its composition follows transparent English noun-modifier + noun + noun patterns rather than an idiomatic or metaphorical shift, so a learner who knows the constituent definitions can infer the MWE meaning.

Etymology

The noun tetrachoric correlation coefficient comes from the picture of two 'yes/no' measures that make a simple 2 by 2 table, with tetra- meaning 'four' for the four boxes. It estimates how strong a 'hidden' link under the surface is between the two things, so the name helps you remember it measures that hidden correlation.
