Morphology

dark + horse

The sense 'an unexpected or little-known winner' is not predictably built from 'dark' (suggesting color, secrecy, or negativity) plus 'horse' (the animal); a learner who knows the literal meanings would most likely infer something like a mysterious or hidden animal, not a surprise contender. The expression is idiomatic (historically from horse‑racing usage) and varies cross‑linguistically, so its conventional meaning is not transparently derivable by a B1 learner.

Etymology

The noun dark horse comes from old horse races where a dark horse was a horse people did not know about before the race. When such a horse won, it surprised everyone, so today 'dark horse' means a person or team little known who unexpectedly succeeds.
