Morphology

significant + impact

The phrase 'significant impact' is directly compositional: 'significant' (important/large enough) modifies 'impact' (an effect), yielding the straightforward meaning 'a major effect' that a B1 learner who knows both words can infer. The adjective+noun pattern is common cross-linguistically and follows standard semantic combination, so the meaning is immediately transparent.

Etymology

Significant impact brings together significant meaning 'important' and impact meaning 'a strong hit'. Imagine a large rock hitting water and making a big splash that changes the surface, so that image helps you see why 'significant impact' means a major or noticeable change.
