Etymology

The word "foundational" derives from "foundation," which originates from the Latin "fundatio" (from "fundare," meaning "to lay a base"). The suffix "-al" (from Latin "-alis") turns the noun into an adjective, indicating a quality or relation. Thus, "foundational" literally means "pertaining to a base," reflecting its role in describing something fundamental or underlying.
