Inherited from Latin iste, either through the accusative istum or a popular (Vulgar Latin) form *istus. Compare Italian esto (older form) and Spanish este.
ăst m or n (feminine singular astă, masculine plural ăști, feminine and neuter plural aste)
Not commonly used anymore outside of a literary and/or popular regional context; rather, the variant ăsta is used more often. Functions as a demonstrative adjective when used in front of a noun. Use ăsta when as a pronoun (or adjective/demonstrative as well, in which case it goes after the noun).
Also used in certain compositions such as astăzi (“today”), astă-seară (“this evening”), astădată (“this time”), astă-vară (“last summer”), astă-noapte (“last night”) etc.
