空想
くうそう
- flat (heiban)
How to read it: a line over a kana means the voice is high there, and ↓ marks where it drops. A kana with no line is low. With no ↓ the pitch stays high to the end and does not drop even on a following particle (が, は).
daydream, fantasy

Not settled
Wiktionary itself hedges on part of this word's origin — those lines are marked below.
- “Ultimately from Middle Chinese 空想 (khuwng sjang^X, literally “fictional, fabricated + think, thought”).”
- Hedged“The sense of fantasy is first cited in Japanese to 1886, and probably reflects a Rangaku and Meiji era style of repurposing older terminology to translate unfamiliar Western concepts.”
- “The Buddhist sense is older, and was borrowed into Japanese along with various Chinese Buddhist texts. This term is included in the 摩訶止観 (Maka Shikan), better known in English by its Chinese pronunciation, the Mohe Zhiguan, completed some time in the early 600s.”
