Morphology

strike + a + blow

The sense 'to have a significant effect' is directly derivable from 'strike' (to hit or attack) + 'blow' (a strong hit), with the determiner 'a' not changing meaning; learners can easily map this to a metaphorical 'hit' against an idea or system. This hit-as-impact metaphor is common across languages and uses straightforward composition, so a B1 learner who knows the constituents would likely infer the MWE meaning.

Etymology

Strike a blow comes from the simple image of hitting something: to strike is to hit and a blow is the hit itself. So the phrase now means 'to do something that hurts or weakens' an idea, group, or system.
