     Oh shut up, Wally, Candy was thinking, although she understood why he couldn't stop babbling. He was unused to an environment he couldn't instantly brighten; he was unused to a place so despairing that it insisted on silence. He was unused to absorbing a shock, to simply taking it in. Wally's talk-a-mile style was a good-hearted effort; he believed in improving the world – he had to fix everything, to make everything better.

   Synonyms: unacquainted (with), unfamiliar with

   Antonyms: acquainted (with), familiar (with)

Usage notes

The second pronunciation (/-u?st/) is used for the “not accustomed” sense (especially in informal speech), and is a devoicing of the terminal /zd/ to /st/ under the influence of the /t/ of the following to. In very informal situations the final stop is often elided completely, leading to the pronunciation of “unused to” as a single word /??n.ju?s.t?/. In formal speech the second (/-u?st/) pronunciation is frequently proscribed in favour of the fully voiced (/-u?zd/) pronunciation, which is acceptable for either sense and is normally used for the “not used” sense in all registers.
