The spelling of the word "dike" can be confusing, as it can have two different pronunciations and therefore two different spellings. When referring to an embankment for holding back water, it is pronounced /daɪk/ and spelled "dike" in American English, while in British English it is pronounced /dʌɪk/ and spelled "dyke." However, when referring to a narrow channel of water, it is pronounced and spelled the same in both American and British English – /daɪk/.
A dike, also known as a dyke, is a noun that refers to a long, narrow embankment built to control or confine water, typically found alongside rivers, lakes, or the sea. Designed for flood protection or to prevent the spread of water, dikes serve as barriers that prevent flooding of adjacent lands. Typically made with compacted soil, clay, rocks, or concrete, dikes are engineered to sustain water pressure and resist erosion, providing stability and security to the surrounding environment.
Dikes have been utilized by civilizations for centuries, beginning with the ancient Egyptians who built earthen embankments called "levees" to protect their agricultural fields from the annual flooding of the Nile River. Over time, dike construction techniques evolved, and various methods and materials have been employed to strengthen their effectiveness.
Apart from flood protection, dikes also play a crucial role in land reclamation, creating polders by enclosing an area of water and enabling it to be drained and converted into arable land. Additionally, dikes may function as part of a transportation system, such as roads or railways, providing connectivity between areas separated by water bodies.
In a figurative sense, the term "dike" can also be used to describe any obstacle or barrier that prevents the flow or spread of something, whether it be physical, metaphorical, or abstract in nature.
• A mound of earth or stones to prevent low lands from being inundated by the sea or a river; a ditch; rock or stony matter running into a seam of coal, or breaking the course of a lode or vein of metal, so as to interrupt its further working in that direction; igneous rock found penetrating stratified rocks; a wall.
• To surround with a barrier.

The word "dike" has its origins in the Old English word "dic", which referred to a trench or ditch created for drainage purposes. The term can be traced back further to the Proto-Germanic root "dik", meaning "trench or ditch". This Proto-Germanic word likely has its roots in the PIE (Proto-Indo-European) root "teig", which means "to knead or shape". In Old English, the word "dic" gradually evolved to "dike" and retained its meaning as a ditch or embankment. Over time, its usage expanded to include the sense of a structure built to control or constrain water, resulting in the modern meaning of "dike" as a barrier or protective embankment.
