5. Etymology: from Middle French vaste, from Latin vastus, "immense, extensive, huge"; also, "desolate, unoccupied, empty".

Latin vastus (short "a") is said to have been distinct from vastus (long "a", [VAYS tuhs]), "desolate"; however, the two forms apparently merged early in Latin, so that the English vast is related to "waste", as in Old English weste, "desolate". The Latin vastus is believed by some scholars to originally have meant "empty, unoccupied, deserted".

To repeat: the sense of "huge", in which English borrowed "vast", is a secondary semantic development.

The two meanings were probably originally attached to two separate words; as stated previously, one with a long -a- and the other one with a short -a-, which merged in early Latin.
