Morphology
The phrase is compositionally built from 'metric' (relating to measurement/distance) and 'function' (a mapping), so a learner who knows both constituents can infer it denotes a mapping that defines distances. This noun–noun technical compound follows regular English formation (cf. 'distance function') and is cross-linguistically parallel, making it transparently interpretable.
Etymology
The term metric function is like a math ruler: a metric (a way to 'measure') and a function (a simple rule) that together 'measure' the 'distance' between two points. That's why a metric function tells us whether points are close or far.
