aloof Aloof and unfriendly.

1859, Charles Dickens, The Haunted House

Jack Governor, always a man of wonderful resources, was Chief Cook, and made some of the best dishes I ever ate, including unapproachable curries.

Often, I say, have I wavered in my faith as to the unapproachable beatitude of bachelorism, when dining out, for example, at a well-appointed marital menage.
