Word Origin & History
A variant of dike, from Northern Middle English dik and dike (“ditch”), from Old Norse díki (“ditch”). Influenced by Middle Dutch dijc (“ditch; dam”) and Middle Low German dīk (“dam”). See also ditch.
Ultimately from Proto-Germanic *dīkiją (“trench, ditch”), from Proto-Indo-European *dʰeygʷ- (“stick into, pierce; dig, stick a spade into”). The semantic evolution (also seen in several cognate words) was from "stick (a spade) into" to "dig" to "hole or other product of digging", "excavation", then the ridge of earth created when excavating a ditch, then to a ridge of earth intended to prevent flooding.
