"beyond or different from what is natural," 1570s, from Medieval Latin preternaturalis (mid-13c.), from Latin phrase praeter naturam (praeterque fatum) "beyond nature (and beyond fate)," from praeter "beyond, over, more than in quantity or degree" (see preter-) + accusative of natura "nature" (see natural (adj.)).
Used at least since 1770s in the sense of supernatural, but technically and properly distinct from that word. "Preternatural is used especially to note that which might have been a work of nature, but is not" [Century Dictionary]. Related: Preternaturally; preternaturalness; preternaturalism.
title applied to an adept in Brahmanism, literally "great-souled," from Sanskrit mahatman, from maha "great" (from PIE root *meg- "great") + atman, "soul, principle of life," properly "breath" (see atman). In esoteric Buddhism, "a person of supernatural powers." In common use, as a title, a mark of love and respect. Said to have been applied to Gandhi (1869-1948) in 1915, perhaps by poet Rabrindranath Tagore. The earliest use of the word in English, however, is among the theosophists, who applied it to certain imaginary beings with preternatural powers (1884).
