coastal
UK: ˈkəʊstl | US: ˈkoʊstl
adj. relating to or situated near a coast
adj. characteristic of the coast (e.g., climate, vegetation)
The word "coastal" derives from "coast," which originates from the Latin costa (rib, side, or flank), later evolving in Old French to coste (edge or border). By the 14th century, "coast" in English referred specifically to the shoreline. The suffix -al (from Latin -alis) was added to form the adjective, indicating a relationship to the coast. This logical progression—from a general "side" to a geographic boundary and finally to its descriptive form—reflects the word's functional adaptation in English.
