Variants and Related Words

Synonyms

• For the water barrier: Embankment, levee, dam, barrier, seawall.

Important Note on Usage

• The term "dyke" as a noun for a lesbian is a pejorative slur. Its use is offensive and unacceptable in respectful discourse. The reclaimed use by some within the LGBTQ+ community does not grant general permission for others to use it. The primary and non-offensive meanings of "dyke"/"dike" relate to water management and geology.
