Morphology
close + the + stable + door + after + the + horse + has + bolt
The literal phrase describes a scenario—shutting a stable door after the horse has already escaped—that directly models taking action too late, so a learner who knows the words can often infer the general meaning. However, it is a conventional proverb requiring metaphorical mapping and some cultural background (stables/horses), so the judgment is not fully predictable for all B1 learners.
Etymology
Close the stable door after the horse has bolted comes from a simple farm picture: the horse has already bolted, or 'run away', and only then someone closes the stable door. So, it means 'to do something too late'.
