Outside Of

We stood outside of the building. Make it outside the building. In sentences indicating location, "of is superfluous with outside," says Roy H. Copperud. His fellow English scholar Theodore M. Bernstein calls outside of "a substandard casualism." With sentences where outside of is not literal, such as Outside of you, I have no one, there are better alternatives available, including except for, other than, besides, apart from, and aside from.
