The word "esper" carries a variety of connotations in literature, simultaneously serving as a proper name, a scientific citation, and a verb imbued with emotional or anticipatory nuance. In narrative fiction, it often appears as a character’s name—as with Cousin Esper or the recurring figure Esper Indiman—lending an air of mystery and individual identity to those who bear it ([1], [2], [3]). In scholarly texts, especially within zoological or botanical contexts, "Esper" functions as an abbreviated authority, citing revisions or discoveries in taxonomy ([4], [5]). Meanwhile, in Spanish-language writings, its roots in the verb "esperar" evoke the act of waiting or expecting, deepening the text’s emotional texture ([6], [7]). Moreover, in science-fiction realms, "esper" sometimes denotes individuals with extrasensory abilities, thereby extending its semantic range into the realm of the psychic ([8], [9]).
