I know a native English speaker who seems to have lost touch with English. I am not sure how great her command of the language was to start with, but to use one of her favorite words, she appears now to be “dabbling” in it.
Choice selections of her misuse:
“We may not have made it aware”. She means, “We may not have made you aware of it.” Somehow she has lost all sense of direct and indirect object use.
With regard to hiring outside contractors:
“Did we do the study in-house or outhouse?”
Need I say more?
