原作, 翻案 and 脚色: source works, adaptation and embellished facts
Compare 原作 as a source work with 翻案 as adaptation and 脚色 for a novel or facts. Distinguish a changed ending, a rewritten work and a request to stop embellishing.
原作 as the source novel and a different ending
原作 (げんさく) means original work or source material. 「映画を見る前に原作の小説を読んだ。」 means “I read the original novel before watching the movie.” The reported action is reading the source novel before watching its film version; the sentence does not separately report completion of the viewing.
「舞台版では原作と異なる結末が用意されている。」 means “The stage version has an ending different from the original work.” The different ending belongs to this stage version. It identifies a relationship with the source work rather than a rule that every adaptation must change the ending.
翻案 in adaptation and comparison
翻案 (ほんあん) means adaptation. 「昔話を現代の舞台劇に翻案した。」 means “We adapted the old story into a modern stage play.” An old story was adapted into a work for the modern stage. The work's transformation is distinct from a change to when the original story itself existed.
「原作と映画の翻案部分を比較した。」 means “We compared the adaptation in the film with the original.” The comparison concerns the adaptation in a film and the original. Comparing those parts is a different action from creating the modern stage play in the first example.
脚色 applied to a work or to facts
脚色 (きゃくしょく) means adaptation or embellishment. 「古い小説を現代の舞台向けに脚色した。」 means “We adapted the old novel for a modern stage.” The old novel is the object adapted for the modern stage in this example.
「事実を面白く脚色して話すのはやめてほしい。」 means “Please stop embellishing the facts to make the story more interesting.” Here the object is 事実, the facts, and the speaker requests an end to embellishing them. The request does not report that the embellishing has already stopped.
Does 脚色 in 事実を面白く脚色して話すのはやめてほしい mean adapting a novel for the stage?
Show the answer and why
Here it means embellishing facts when telling them. The object differs from the novel adapted for the stage, and the speaker's request to stop does not report that the requested change has already happened.
