Morphology

sea + mile

The compound directly combines 'sea' (maritime) with 'mile' (unit of distance), so a learner who knows both words will readily infer it denotes a mile used at sea. Although the exact historical length (6,000 feet) is a specific detail learners cannot deduce, the basic meaning is fully compositional and cross-linguistically familiar (cf. 'nautical mile'), making it transparent.

Etymology

Sea mile comes from sailors naming a special 'mile' used at sea — they put sea before mile to show it was the ship's measure. So sea mile came to mean an old unit of about 6,000 feet, which was shorter than the modern mile used at sea.
