inure

in-YOOR/ˌɪnjˈʊr/

To make someone accustomed to something difficult or unpleasant.

Repeated tasting inures the woman to the coffee's bitterness.

Two small sequential vignettes show the same woman becoming accustomed to bitter black coffee: first she winces after a sip, then she drinks it calmly.
Etymology

“In ure” meant “in practice,” and putting something into practice meant establishing it by use. Becoming accustomed through use developed into being toughened or hardened by experience, especially something unpleasant.
