Furthermore, both Russian and Spanish are prodrop languages (Haspelmath, 2001) and share syntactic phenomena, such as dative subjects (Moore and Perlmutter, 2000;Melis et al., 2013) and differential object marking (Bossong, 1991), which might explain why ES is closest to RU overall.
english appears remarkably isolated from all languages, equally distant from its germanic (De) and romance (FR) cousins.
