Etymology
Origin of fantastic
First recorded in 1350–1400; Middle English fantastik “pertaining to the imaginative faculty,” from Medieval Latin fantasticus, variant of Late Latin phantasticus, from Greek phantastikós “able to present the appearence (of something),” derivative of phantázein “to make present to the eye or mind” (akin to phānós “light, bright,” phaínein “to bring to light, cause to appear”) + -tikos -tic
Explanation
The adjective fantastic has two meanings — extraordinarily brilliant or ludicrously far-fetched. So when your boss calls your suggestion of work-at-home-in-your-bathrobe-Fridays for the whole office fantastic, be sure you know which one he means. We get fantastic from the Latin phantasticus, meaning “imaginary.” Sometimes it’s still used that way: If you call a unicorn a fantastic beast, you’re not paying it a compliment; you’re saying it exists only in fairy tales. Most often, though, fantastic means strikingly out-of-the-ordinary. It can be complimentary ("You got an A? Fantastic!") or disparaging ("He was always foolishly unrealistic, but trying to reach the moon using a balloon tied to his bicycle was his most fantastic idea yet.").
