Morphology

three-mile + limit

The phrase is fully compositional: 'three-mile' denotes a distance of three miles and 'limit' means a boundary, so a learner who knows the constituent words can derive that it refers to a boundary three miles from the coast. This measurement + boundary construction is common and follows regular English compounding patterns, making the meaning transparent to B1 learners.

Etymology

Three-mile limit comes from an old rule that a country said it owned the sea as far as a cannon could fire from the shore—about three miles—so the three-mile line became the country's water limit, meaning the 'boundary' of its waters.
