Fictionalize comes from fictional + -ize, ultimately from Latin fictio ('a fashioning, feigning'), from fingere ('to shape, form, feign'), from Proto-Indo-European *dʰeyǵʰ- ('to knead, form'). Morphologically, the account is both compositional and suffixal: -ize marks the visible structure by which the older base becomes the modern form. In present use, it is used as a verb meaning "to turn real events into a fictional narrative", so the historical material remains connected with the current sense rather than standing as bare ancestry. The wider English family includes derivatives such as fictionalization and fictionalized and related forms such as fiction, fictional, and fictitious, showing how the same historical material continues to organize neighboring vocabulary. The named historical forms include Latin fictio, Latin fingere, and Proto-Indo-European *dʰeyǵʰ-, keeping the history tied to concrete forms rather than a loose resemblance.
