Build castles in the air
Meaning
To dream or plan fanciful, unrealistic schemes that are unlikely to ever come true.
Origin
The imagery of grand, impossible schemes has roots stretching back to ancient fables, notably from the 12th-century Sanskrit collection, the Panchatantra, where a dreaming Brahmin shatters his pots while envisioning future wealth. This narrative journeyed westward, inspiring European authors. The phrase truly crystallized in the popular imagination through works like Jean de La Fontaine's 17th-century French fable, “The Milkmaid and the Pot of Milk.” In this tale, a milkmaid daydreams of future prosperity, building an elaborate fantasy until she trips and spills her milk, destroying her imagined fortune. This vivid depiction of ambitious, yet baseless, plans firmly established the phrase in the English lexicon, painting a clear picture of dreams constructed on nothing but thin air.
