To make something more decorative, stylish, or elaborate; to dress up or embellish something.
From 'fancy' (something decorated or stylish) plus the verb-forming suffix '-ify' (to make). This is a productive suffix that transforms nouns and adjectives into verbs meaning 'to make into' the quality described.
The suffix '-ify' is one of English's most productive tricks—you can 'fancify,' 'beautify,' 'simplify'—and people keep creating new '-ify' verbs, like 'to sanitize' or 'to monetize'!
