Gk. legein “to say, tell, speak, declare,” originally, in Homer “to pick out, select, collect, enumerate;” lexis “speech, diction;” logos “word, speech, thought.”

Etymology (PE): Huš, from Mid.Pers. hôš “intellect, understanding; mind,” from Av. uši- “intelligence, understanding; mind,” uši.darθra- “holding in mind.”
