Morphology

high + sea

The combination of 'high' (suggesting far or elevated) and 'sea' (the ocean) gives a partial clue that this refers to open or away-from-shore waters, so a learner can guess a general spatial sense. However, the specific legal/ jurisdictional meaning 'beyond territorial waters' is not directly derivable at B1 without prior exposure, even though many languages use a similar literal phrase, so the expression is only partly transparent.

Etymology

High sea comes from the picture of the high wide sea far from land, where ships sailed out of sight of any coast; that open water was seen as outside a single country's reach, so today high sea means the 'open sea' 'beyond a country's waters'.
