Inure is a verb that means to become accustomed to something unpleasant.

Our word of the day’s origin is from the Latin word opera (OH per uh) which means ‘work.’ From there it evolved into a word that means ‘to become accustomed to.’

Inure is generally used with a subject, meaning we usually become inured to something, as in:

I didn’t like coming in at six and working until two in the morning, but after all those years of working the graveyard shift at the convenience store, I had become inured to working late hours.
