unfounded
UK: ʌnˈfaʊndɪd | US: ʌnˈfaʊndɪd
adj. lacking a basis in fact or reason; groundless
adj. not established or founded
The word "unfounded" combines the prefix "un-" (meaning "not"), the root "found" (from Old French "fonder," meaning "to establish or base"), and the suffix "-ed" (forming adjectives). Originally, "found" traces back to Latin "fundare" (to lay a base), derived from "fundus" (bottom or foundation). The term evolved to describe ideas or claims lacking a factual or logical foundation, emphasizing their absence of support.
