inalcanzable
unreachable, unattainable
adjective ee-nahl-kahn-SAH-bleh Rare
Usage Note
Inalcanzable combines the prefix in- (negation) with alcanzable (reachable), from alcanzar (to reach). It is invariable for gender ('un sueño inalcanzable', 'una meta inalcanzable') and its plural simply adds -s. It is stronger than difícil de alcanzar and implies true impossibility, not mere difficulty.
Examples
"Su sueño parece completamente inalcanzable."
Natural Translation
Her dream seems completely unattainable.
