A raised bank of earth, stone, or other material built to prevent flooding or to carry a road or railway. An artificial ridge constructed along a river or coast for protection or transportation.
From the verb 'embank' (to enclose with a bank) plus the suffix -ment. The word emerged in the 17th century during major European infrastructure projects, combining 'em-' (variant of 'en-') with 'bank' from Old Norse bakki.
