Morphology

inflection + point

The compound meaning is directly built from 'inflection' (a change in curvature or direction) + 'point' (a specific moment or stage), so a learner who knows those constituent senses can infer a 'turning point' or moment of significant change. The metaphorical mapping is regular and exists in many languages (e.g., Spanish punto de inflexión, French point d'inflexion), making the composition readily comprehensible rather than idiomatic.

Etymology

Inflection point comes from math, where a curve bends and changes direction at a single point called an inflection. So, it means a moment when a situation reaches a 'turning point' or makes a big change.
