hasta.

Inherited from Old Spanish fasta, and of ultimate uncertain origin. Commonly proposed etymologies are Arabic حَتَّى (ḥattā, “until”) and Latin ad ista (“to this”). According to Coromines & Pascual (1980:323-324), fasta is first attested with certainty in the 13th century (dubiously earlier since 1074), with variants fata (att. 1098 as hata, Auto de Reyes Magos), adte (att. 1050, very rare), ata (att. ca. 1000, Glosas Emilianenses), adta (att. 945, in a Cardeña document). A(d)ta predominates in pre-literary (pre-13th century) texts, then in the 13th c. there is increasing vacillation between a predominant fata and the variant fasta until fasta becomes established in the 14th c. They propose st as dissimilation of the earlier dt in adta, attempting to render the Arabic geminate tt, and the initial f- (i.e. /ɸ ~ h/) found in various forms renders the initial Arabic /ħ/ of ḥattā. Cognate with Old Galician-Portuguese ata, ate (stressed as até?), atẽe, atẽes, atães; Portuguese até; Galician ata, até, atá, asta, astra; Mirandese ata; Asturian fasta, ata; Valencian dasta, hasda, handa. Viaro (2013) proposes a derivation of fasta from Latin faciem + Latin intrā, after these reduced to faz + t(r)a, cf. Spanish hacia, pointing out Old Spanish adtor became azor instead of *astor. Meanwhile, the mostly pre-13th century a(d)ta would be from Latin ad + intrā, cognate with Old Galician-Portuguese atra and ata.
