Comments: Vasconists agree that this pronoun was originally 2nd person plural, changed to singular (polite) in present-day Bsq, following the spread of a "T-V distinction" in western Europe. Some dialects (SAL, BNV-Garazi) also have a palatalized variant xu [šu], "intermediate in familiarity between hi and zu" (Trask 1997: 96). A new 'you' (plural) has developed by the addition of the plural marker -k: (c) zu-ek, etc. Cf. PNC *źwĕ 'you (2d p. plur. pron.)'.
