phantasm

Etymology

It is inherited from Middle English fantesme, later fantasme,^[2] borrowed from Anglo-Norman fawntesme, with Anglo-Norman and Old French fantasme and fantosme,^[3][2][4] and directly borrowed from Latin phantasma (“ghost, apparition”),^[3][2][4] which is from Ancient Greek φάντασμα (phántasma, “appearance, vision, dream, ghost”),^[3] from φαντάζειν (phantázein, “to make visible”),^[3][5][6] from the stem of φαίνειν (phaínein, “to show”),^[3][5][4] from Proto-Indo-European *bhā- (“to shine”).^[5][6][4] The Anglo-Norman fantosme is recorded from the first third of the 12th century.^[7] The Latin noun meant a mental image, a figment and an illusion only in post-classical use, in Augustine.^[3] The modern spelling follows the Latin: the Oxford Dictionary of English and Etymonline place the change in the 16th century,^[8][4] and Barnhart dates phantasm to 1614, after phantasma in 1598.^[2] The OED compares Old Occitan fantasma, Spanish fantasma and Italian fantasma,^[3] and Klein and Etymonline call phantom a doublet.^[5][4]

Earliest recorded meaning

Illusion, deceptive appearance: before 1250, in the Ancrene Riwle.^[3][2] Etymonline dates it to the mid-13th century, as something with only seeming reality.^[4]

Semantic evolution

The word began as a mass noun for illusion, a use the OED now calls rare.^[3] It soon became countable, for a thing that seems to exist but does not (before 1398),^[3] and then an apparition or ghost (about 1430),^[3] which Etymonline already finds about 1300.^[4] Hoad traces the same path: illusion in the 13th century, ghost and imagination in the 15th, mental image in the 16th.^[9] Philosophy took it up in 1594 for a mental image regarded as the immediate object of perception,^[3][10] and Collins records its use for reality as distorted by perception in Plato's philosophy.^[11] Other uses did not last: imagination or fancy from 1490 to 1689, an impostor from 1622 to 1641, in Bacon's Henry VII, and an adjective meaning illusory from 1834 to 1871, in Carlyle.^[3] The proceedings of the Society for Psychical Research show a new technical use in 1884, for the vision of an absent person, especially by telepathy.^[3]
