(in Spanish America) a man who owns considerable property or is otherwise esteemed.
Origin: 1585–95; < Sp, contr. of hijo dalgo, OSp fijo dalgo a noble, a person with property, a son with something < L filius son + dē from + aliquō something
1594, from Sp., from O.Sp. fidalgo, shortened from filho de algo "son (L. filus) of someone (L. aliquis)," perhaps an imitation of Ar. ibn-nas "son of people," a complimentary title.
