The story
From a- (prefix meaning ‘opposite of; without’) + phantasia, from Ancient Greek ἀ- (a-, prefix forming words having senses opposite to the stems or words to which the prefix is attached) + φᾰντᾰσῐ́ᾱ (phăntăsĭ́ā, “appearance, look; image; impression, perception”). Φᾰντᾰσῐ́ᾱ (Phăntăsĭ́ā) is derived from φᾰ́ντᾰσῐς (phắntăsĭs) + -ῐ́ᾱ (-ĭ́ā, suffix forming feminine abstract nouns); and φᾰ́ντᾰσῐς (phắntăsĭs) from φᾰντᾰ́ζω (phăntắzō, “to make visible, show; to become visible”), from φᾰντός (phăntós, “visible”), from φαίνω (phaínō, “to cause to appear, reveal; to give light, shine”), ultimately from Proto-Indo-European *bʰeh₂- (‘to be visible, appear; to shine’). The English word was coined by the British neurologist Adam Zeman (born 1957) and his collaborators Michaela Dewar and the Italian neurologist Sergio Della Sala (born 1955) in a 2015 article published in Cortex.
