语源 (Etymology)
Origin:
From Latin fantasticus (meaning "imaginary"), derived from Greek phantastikos (ἀphantαστικός, meaning "pertaining to the faculty of imagination" or "able to imagine"). 中文翻译: 词源：源自拉丁语 fantasticus（意为“想象的”），可追溯至希腊语 phantastikos（意为“与想象能力相关的”或“能够想象的”）。
Historical Shift:
In the 16th century, the term first entered English with the meaning "unreal" or "imaginative" (reflecting its Greek/Latin roots). Over time, particularly in the 20th century, it developed a secondary, positive connotation of "extremely good," an example of semantic amelioration (the process of a word taking on a more favorable meaning). 中文翻译: 历史演变：16世纪初入英语时，词义为“不真实的”或“富有想象力的”（体现其希腊/拉丁语根源）。随着时间推移，尤其在20世纪，衍生出“极好的”这一积极含义，属于语义改善（词语词义向更正面方向演变的过程）。
