The Spanish preposition 'hasta' meaning 'until' has an interesting dual etymology, showing influence from both Arabic and Latin sources during Spain's complex linguistic history. It comes from both the Andalusi Arabic 'ḥattá' (meaning 'until'), which itself derives from Classical Arabic 'ḥatta', as well as the Latin phrase 'ad ista' meaning 'until this'. This is a fascinating example of how Spanish vocabulary was shaped by both Romance and Arabic influences during the centuries of Muslim presence in the Iberian Peninsula. The similar meanings of both source terms likely helped facilitate their merger into the modern Spanish word.

Unlike many Spanish words, 'hasta' stands somewhat alone in modern Spanish vocabulary without many common related words, as it was borrowed as a functional preposition rather than as part of a larger word family.

There aren't any commonly used English words directly related to 'hasta', as its origins lie in Arabic and Latin terms that didn't make their way into English. English uses different Germanic-derived words like 'until' or 'to' to express similar concepts.
