British spelling: to convert something real or factual into a fictional narrative.
From 'fiction' with the productive causative verb-forming suffix '-ise' (British) or '-ize' (American). Emerged in the 19th century as a way to describe turning history or biography into stories.
Authors 'fictionise' true events constantly—like how 'The Crown' fictionises recent royal history—and this word captures that specific act of blending fact and fabrication.
