What does fantasy mean?
Fantasy refers to the mind's power to imagine things that depart from reality — whether idle daydreams, elaborate invented worlds, or hopes that are plainly unattainable. In its broadest sense it names the imaginative faculty itself; in popular culture it designates a genre of fiction populated by magic, mythical creatures, and secondary worlds, exemplified by works from Tolkien to modern game settings. The word can carry a critical edge when applied to beliefs or plans: calling something 'a fantasy' implies it is detached from facts and destined to disappoint. At the same time, fantasy is celebrated as the engine of art, literature, and innovation, since every invention begins as something imagined before it becomes real. Its everyday derivatives — fantasize, fantastical, and the older clipped form 'fancy' — keep the concept woven through ordinary speech, from 'fantasy football' leagues to 'flights of fantasy' in architecture and rhetoric.
The imaginative capacity to conceive of things absent from, or impossible within, reality; an instance of such imagining.
"The film trades in nostalgia-fueled fantasy about a simpler, gentler past."
In psychological contexts, the older spelling 'phantasy' may appear.
A genre of fiction featuring magic, supernatural elements, and invented worlds.
"She has published widely in fantasy and science fiction."
Often used attributively, as in 'fantasy literature' or 'fantasy series.'
The regular plural applies both to instances of imagined scenarios and to works within the genre.
"The therapist helped him separate harmless daydreams from darker fantasies."
The word 'fancy' isn't just a cousin of 'fantasy' — it literally began life as it, worn down by centuries of English speakers who couldn't be bothered with all those syllables.

Etymology of fantasy
Fantasy descends ultimately from the ancient Greek noun phantasia, meaning appearance or imagination, derived from the verb phainein, 'to show' or 'to make visible.' The Greek term passed into Latin as phantasia and reached medieval English through Old French fantasie, entering English in the Middle Ages. A clipped form, 'fancy,' split off in later medieval usage and developed a life of its own, while related terms such as phantom and phantasm preserve the same Greek lineage. The modern sense of fantasy as a literary genre is largely a product of the twentieth century.

How fantasy is actually used
Fantasy is neutral in most contexts, but when applied to hopes or plans it often carries a mild negative connotation of escapism or self-deception ('it's pure fantasy to expect...'). As a literary label, however, it is a straightforward descriptive term. In psychology, the spelling 'phantasy' is sometimes retained for unconscious imagined content.
Easily confused with fantasy
Fancy historically arose as a clipped form of fantasy and now usually denotes a whim, liking, or ornamental imagination rather than elaborate imagined scenarios.
Phantasy is simply an older spelling variant of fantasy, still used in psychoanalytic writing to mean an unconscious imagined scenario.
