Morphology

sea + change

The headword 'change' gives the general sense of alteration while 'sea' contributes a metaphorical sense of vastness or scale, so a learner could infer that the phrase denotes a large or significant change. However, the specific nuance of a profound, notable transformation is idiomatic and historically rooted, so a B1 learner who only knows the literal words may not reliably derive the exact meaning.

Etymology

Sea change comes from a poem by Shakespeare where the sea seems to change a body lost at sea into something new and strange. So now sea change means a big, deep 'change' in the way things are.
