Origin: 1350–1400; ME al redy all ready; what orig. meant “completely ( all ) ready” and modified the subject (The porter all ready was there) was taken adverbially as modifying the predicate (The porter already was there, meaning “from an earlier time”) Usage note: Although already and all ready are often indistinguishable in speech, the written forms have distinct meanings and uses.
