"to curse, imprecate evil upon," hence "to detest utterly, abominate," 1560s, from Latin execratus/exsecratus, past participle of execrari/exsecrari "to curse, utter a curse, take a solemn oath with imprecations; hate, abhor," from ex "out" (see ex-) + sacrare "to devote to" (see sacred). Hence, "to devote off or away; to curse." Compare consecrate. Related: Execrated; execrating.
