Morphology

stop + (someone) + in + (their) + track

The verb 'stop' combined with the locative phrase 'in (their) tracks' transparently conveys causing someone to halt on their path, so a learner who knows the constituents will likely infer a meaning related to sudden cessation of movement. However, the conventionalized nuance that this halting is abrupt and often due to surprise or shock, and its frequent metaphorical extension to non-physical actions, is somewhat idiomatic and not fully predictable, making the expression only partially transparent to a B1 learner.

Etymology

Stop (someone) in (their) tracks comes from a simple picture: imagine a person walking along a path or a railway and suddenly freeze, so they literally stop on the tracks. That's why it means 'to make someone suddenly stop what they are doing or thinking', usually because they are surprised or shocked.
