Morphology
product-moment + correlation + coefficient
A learner who knows 'correlation' and 'coefficient' can infer this refers to a statistical coefficient measuring the strength/direction of a relationship, so that core meaning is relatively transparent. However, the hyphenated modifier 'product-moment' is technical and not predictable from basic word meanings (it denotes a specific computational form, as in Pearson's product–moment), so the full term is not fully derivable without exposure.
Etymology
Product-moment correlation coefficient is named for how it is made: you multiply numbers, the product, that show how each value differs from the average, a kind of moment, and this gives one number that shows the link between two things. So the name helps you remember it measures 'how strongly two things move together in a straight line'.
