Synonyms Imagination, Fancy. By derivation and early use fancy has the same meaning as imagination, but the words have become more and more distinctly separated. (See Wordsworth's preface to his “Lyrical Ballads.”) Imagination is the more profound, earnest, logical. Fancy is lighter, more sportive, and often more purely creative. We call “Hamlet” and “Macbeth” works of Shakspere's imagination, the “Midsummer Night's Dream” and “The Tempest” of his fancy.n. In entomology, the act of transforming into an imago or of reaching the imaginal stage: said of insects completing their metamorphosis.
