  • before (adv., prep.) Old English beforan "in front of, in former times; in the presence of, in front of in time or position," from Proto-Germanic *bi- "by" (see by) + *forana "from the front," adverbial derivative of *fora (from PIE root *per- (1) "forward," hence "in front of, before"). Compare Old Frisian bifara, Old Saxon biforan, Old High German bifora, German bevor.
