- memory (n.) mid-13c., "recollection (of someone or something); awareness, consciousness," also "fame, renown, reputation," from Anglo-Fr. memorie (O.Fr. memoire, 11c., "mind, memory, remembrance; memorial, record") and directly from L. memoria "memory, remembrance, faculty of remembering," noun of quality from memor "mindful, remembering," from PIE root * (s)mer- "to remember" (Skt. smarati "remembers," Avestan mimara "mindful;" Gk. merimna "care, thought," mermeros "causing anxiety, mischievous, baneful;" Serbo-Croatian mariti "to care for;" Welsh marth "sadness, anxiety;" O.N. Mimir, name of the giant who guards the Well of Wisdom; O.E. gemimor "known," murnan "mourn, remember sorrowfully;" Du. mijmeren "to ponder"). Meaning "faculty of remembering" is late 14c. in English.I am grown old and my memory is not as active as it used to be. When I was younger I could remember anything, whether it had happened or not; but my faculties are decaying now and soon I shall be so I cannot remember any but the things that never happened. It is sad to go to pieces like this, but we all have to do it. [Mark Twain, "Autobiography"]Computer sense, "device which stores information," is from 1946. Related: Memories.
