Believe it or not, but I noticed this only
now:
sur = Rus (as Jansy informed us, sur* is
Spanish for "South," cf. Borges' story El Sur; rus is
Latin for "country" as opposed to city; Rus is the old name of Russia, òÕÓØ,
that occurs several times in ADA: 2.1, 2.2, 5.5; cf. Pushkin's O Rus pun; the
epigraph to the Second Canto of EO).
