Origin:
Old English ūt (adverb), ūtian (verb), of Germanic origin; related to Dutch uit and German aus

The use of out as a preposition (rather than the standard prepositional phrase out of), as in he threw it out the window, is common in informal contexts, and is standard in American, Australian, and New Zealand English. Traditionalists do not accept it as part of standard British English, however.
