Morphology

flash + point

The meaning 'a critical or sudden moment when a situation could escalate' is directly built from 'flash' (a very short, sudden instant) + 'point' (a specific moment or stage), so the composite meaning is predictable from the constituents. This compositional pattern is common cross-linguistically (e.g. equivalents like 'punto crítico'/'point de basculement') and a B1 learner who knows both words would readily infer the idiomatic sense.

Etymology

The term flash point comes from a simple image: heat a liquid until its gas makes a small flash of flame at the exact point when it can catch fire. So, it means the temperature at which the liquid will 'ignite'.
