Pronunciation

  • /ˈfæntəˌsaɪz/[1]
  • US: /ˈfæntəˌsaɪz/[1]

Etymology

It is formed from English fantasy + -ize.[2][3][4][5][6] The noun goes back through Middle English fantasie and Old French fantasie to Latin phantasia, from Ancient Greek φαντασία (phantasía, “power of imagination; appearance, image”), from φαίνω (phaínō, “to make visible”).[4][1] The Shorter Oxford also records the spelling “phantasize”,[7] and Etymonline notes an earlier English verb, fantasticate, from about 1600.[4]

Earliest recorded meaning

To indulge in fantasy, to have fanciful visions: 1926, in the Spectator.[2][3][4] Merriam-Webster dates the transitive sense "to imagine" to the same year.[5]

Semantic evolution

The verb arose in the same years as the sense "daydream based on desires" of fantasy, which Etymonline dates to 1926,[4] and the OED defines its first sense by an older verb use of fantasy.[2] The transitive use, to picture something in fantasy, follows in 1950, in a book on sexual psychology.[2] Dictionary.com dates the word to 1925–30 and notes the chiefly British spelling fantasise.[6]
